Symfony DomCrawler Help Needed (Laravel, PHP)

Hello! I am working on software that crawls specific eCommerce websites and places orders automatically. The work is about 90% done already! What I need from you is to take the list of websites and write classes for each one. Each class will need a function to log in, add a specific product to the cart and checkout (as a guest, using gift card or credit card.) Each class will extend a parent class that has already been written - that covers the basics and not every store will need custom functions to be written. I even have examples of 2 working stores to base the others off of! To be considered, you must be a proven expert in PHP, Laravel and Symfony. Any experience with Symfony DomCrawler and Goutte will be a big plus. If you are interested, please bid and ask as many relevant questions as possible up front. *** Please bid per site! It is undecided how many sites / class will need to be done, so base your price and timeline for one. *** I look forward to working with you!
