Every clip will be sold individually, so the flow must guide a visitor from preview to one-time payment and then straight into their personal viewing area.

Here’s the flow I have in mind. Visitors browse or search a restaurant, land on a profile page, scan through photos, then open a tabbed menu that lists dish names, short descriptions, and prices. When they decide to book, the reservation form asks for party size and time, processes a per-guest booking fee of roughly $1–1.50 through a mainstream payment gateway (Stripe or PayPal are fine), and instantly fires the confirmation to the owner’s email and WhatsApp number—both, not one or the other. ...

For the theme, I’m happy with the overall template but the layout needs tightening, colours should better match the brand palette, and the typography needs a cleaner hierarchy.

    I need an Android application that allows users to send and receive funds quickly, track their full transaction history, and handle multiple currencies inside a single, clean interface. Security is critical: log-in and every sensitive action must be gated by a traditional password plus a four-digit PIN flow. Core scope • Android-only build, coded in Kotlin or Java and compiled in Android Studio. • Real-time money movement between verified accounts. You may connect to an existing payment gateway or build REST endpoints; either way the transfer must settle instantly in a sandbox environment. • Persistent ledger so users can open “History” and filter by date, currency, or status. • Multi-currency wallet: balances, FX conversion at live rates, and clear...

    I have the core pages of an online service–providing site sketched out, but everything still runs manually in the background. I now need the entire flow rebuilt so that it operates 100 % automatically through well-structured API calls. Here is what I expect once the job is done: • Users should be able to register, verify their email or phone, and manage their own profiles without my intervention. • A secure payment gateway must be integrated so that services can be purchased, renewed and, when required, refunded automatically. • Any service logic that currently depends on me pressing a button (for example activating a user’s subscription or sending a service result) has to be triggered through the API layer instead. You are free to choose the stack, prov...

    My WooCommerce store is up, orders flow daily, yet two areas still hold us back and I need someone who already knows the fixes—not someone learning on my clock. First, freight calculations. We rely on the built-in WooCommerce Shipping module, but I must expand the options it returns so buyers can choose the service that truly suits them using our Freight provider API's (LTL, expedited, economy, etc.). Rates need to pull through instantly and display cleanly at checkout without confusing add-ons or hidden fees. Second, customer segmentation. The site will serve three distinct buyer levels—retail, wholesale, and reseller—with tiered pricing and catalog visibility rules for each. Accounts must be auto-assigned to the correct tier after approval, and every tier must...

    I am starting from a beginner level and need to master no-code development in FlutterFlow, tie it seamlessly into Firebase, and round everything off with reliable UPI payment integration. Because my company’s project details are confidential, every explanation must be carried out with dummy data or in a generic sample app; I will then replicate the same steps inside our private repository. Live, one-on-one sessions over a screen-sharing platform are essential. I learn best by working through real examples while asking questions in the moment, so each meeting should be highly interactive and task-driven. We will begin with Flutter UI design fundamentals inside FlutterFlow, then progress through backend setup, Firebase authentication, Firestore/Realtime Database, cloud functions, and ...

Ä.) auf meinen Rechner und richtest alles gemeinsam mit mir ein. • Du aktivierst in Stripe die e...

    My business makes regular international transfers and I want those payments handled through an online service. PayPal is the initial reference point, yet I’m fully open to any other platform that can cut fees, speed up delivery times, and simplify compliance paperwork. The task covers: • A concise comparison of at least three online payment services (PayPal plus two alternatives of your choice) focused on fees, FX rates, transfer limits, supported countries, and API availability. • Step-by-step account setup and verification instructions for the chosen service. • A repeatable workflow—either written SOP or a lightweight script—instructing my team exactly how to initiate, track, and reconcile each transfer. • A short checklist to keep every tra...
