I need an experienced data-gathering developer to assemble a clean, well-structured database of roughly 100,000 companies pulled from Yellow Pages and Google My Business. You may also enrich the list with any reputable open databases that fit the brief. The finished file must arrive as a single, comma-separated CSV ready for import into my CRM. Each row should include: • Company name • Industry / business sector • State / region • City • ZIP / postal code • Email address • WhatsApp number • Phone number(s) • Website URL I’m counting on automated verification tools to weed out duplicates, flag invalid emails and phone numbers, and generally keep the error rate to an absolute minimum. Scraping scripts built with Python (BeautifulSoup, Scrapy, Selenium, etc.) or comparable tooling are fine so long as they respect directory TOS and local regulations. Acceptance criteria • Full CSV delivered, UTF-8 encoded, 100 k ±2 % records • ≥95 % of emails and phone numbers pass automated validation • No more than 1 % duplicate companies across the file If you’ve completed large-scale web scraping or lead-gen datasets before, let me know your approach, suggested timeline, and any questions. I’m ready to move quickly once I know the scope is clear.

I can build a scalable data-collection workflow to assemble and clean a large business dataset while keeping the output structured for direct CRM import. The process would combine automated collection, normalization, deduplication, and validation to produce a UTF-8 CSV containing company details, location fields, contact channels, and website information in a consistent format. For quality control, the workflow can include duplicate detection, email and phone validation, standardized formatting, and reporting on coverage and data quality before delivery. I can also provide the collection scripts and a documented process so future refreshes or expansions remain straightforward and repeatable.

Hello, I built many large scale web scraping and lead generation platforms similar before and I would love if I get the chance to work on your project. I can develop a scalable pipeline using Python, Scrapy, Selenium, BeautifulSoup, PostgreSQL, and automated validation tools to collect, deduplicate, and structure high quality business records into a clean UTF 8 CSV ready for CRM import. My focus will be on data quality, validation, and maintainable scraping workflows. One question I have is whether you already hold the necessary rights or licenses to collect and use data from Yellow Pages and Google Business Profiles for your intended CRM use case, or should the solution prioritize only openly licensed sources? Can we connect over a chat to discuss more about the project? Best regards, Dev Singh

Hi, I read your project details carefully and understand you need around 100,000 company records collected from Yellow Pages, Google Business sources, and reputable open databases, then delivered as a clean UTF-8 CSV ready for CRM import. I can help build the dataset with company name, industry, state/region, city, ZIP/postal code, email, WhatsApp, phone number, and website URL. My focus will be on clean structure, duplicate removal, email/phone validation, and keeping the error rate as low as possible. My approach will be to use compliant data-gathering methods, Python-based scraping where allowed, public directories, open business datasets, and validation tools to clean and verify the records. I will also standardize fields, remove duplicates, validate contact details, and deliver the work in staged batches so you can review quality early. Suggested workflow: 1. Sample: 200–500 records for review 2. Batch 1: 25,000 records 3. Batch 2: 50,000 records 4. Final: 100,000 cleaned UTF-8 CSV I can start quickly and provide the first sample within 24 hours after confirming target country/region and industries. Best regards, Shahadat

Hi, I read your project "100K Company Database Build" and I can help with it. I would focus on backend structure, integrations, and reliable data flow. I noticed the relevant skills include Python Data Entry Web Scraping Data Mining Data Scraping Data Collection. My approach: 1. Review the current setup and confirm the exact requirements. 2. Implement the requested work in a clean, maintainable way. 3. Test the result and provide a clear handover with any setup notes needed. Clarification questions: 1. Which external services, APIs, or payment gateways need to be connected, and will test credentials be available? 2. What backend structure, database, user roles, and admin access should the implementation support? 3. What source systems, output fields, and validation rules should the automation or data flow follow? Best regards, Houssame

I will then run automated verification: email validation, phone number formatting, duplicate removal, and industry classification. The final CSV will be UTF-8 encoded with all 10 fields, 95%+ validated emails/phones, and under 1% duplicates. Please start a chat to share your target countries and any specific fields.

Hello I need more details about the job, but here is a template based on your request: It sounds like you need to automate your data collection to save time and ensure accuracy, rather than manually scraping sites. I have built custom scrapers for similar projects using Python and Playwright, specifically focusing on handling anti-bot measures and clean data output. I can get your data pipeline running efficiently by the end of this week. Are you available for a brief call to discuss your specific data sources? Giáp Văn Hưng
