    I want a clean, responsive website that covers five essentials: Home, About, Shop, Donate, and Booking Consultation. In the Shop I will sell downloadable PDF documents; Donate will accept one-off gifts; Booking Consultation must tie directly into Zoom so appointments trigger calendar invites and the meeting link automatically. For payments I only need credit and debit cards processed through Stripe, with everything configured for my Equatorial Guinea–based account and local currency display where possible. A core piece of the site is a symptom-checker(one-time paid access): • Users pick their symptoms from a dropdown list. • The program cross-matches any three shared symptoms and returns every medical condition that fits. • From an admin panel I must be able to...

    I’m ready to start taking payments on my website, which is built with the Builder app platform, and I need Stripe wired in from scratch. I do not yet have a Stripe account, so the first step will be helping me create and verify one (or walking me through it) and then moving straight into a full integration. Here’s what the job will involve: • Generate and apply the correct API keys for both test and live mode. • Configure the webhook endpoints and any required signing secrets, ensuring all critical events (, , etc.) are captured. • Set the callback / success-cancel URLs in the Builder app backend so customers land in the right place after checkout. • Run end-to-end tests in test mode and then process at least one live transaction to confirm funds se...

    I have a WordPress + WooCommerce site that already carries the brand identity yet it is only half-built. My immediate priority is simple: move the project from partial build to fully operational so I can open the doors and start running the site. Where things stand • Core pages and WooCommerce are installed. • An auction plug-in is present and configured configured. • Checkout flow, payment gateways, shipping rules, email notifications, and front-end polish are incomplete or untested. What I need from you 1. Finish configuring the auction workflow so each new listing counts down from 72 hours, accepts proxy bids, shows real-time bid history, and closes cleanly with winner notification and automated payment request. 2. Integrate secure payments (Stripe is pref...

    My online gambling platform needs a single, well-structured payment module that supports multiple processors and advanced features from day one. The ideal stack would integrate PayPal, Stripe, and Neteller, yet I am open to any additional provider that legally serves the gaming sector. Core capabilities the module must expose: • Recurring payments for membership or subscription stakes • One-click deposits so returning players can fund their balance instantly • Automated payouts to users, with clear audit logs and KYC verification hooks You are free to propose ready-made SDKs, hosted solutions, or custom API bridges—as long as the final result passes sandbox tests for deposits, withdrawals, and chargeback handling, and can be dropped into my existing PHP/JavaS...
