Project Title: Need a functional Bux/PTC website script

I am looking for an experienced developer who can provide and set up a fully functional Russian-style Bux/PTC script.
​Core Requirements:
​Main Features: Surfing, Tasks, Letters, Tests, and YouTube/VK integration.
​Referral System: Multi-level referral program.
​Payment Gateway: Automatic deposit and withdrawal (Payeer, Perfect Money, or similar).
​Admin Panel: Full control over users, tasks, and site settings.
​Security: Script must be bug-free and secure from exploits.
​Note: If you have an existing stable script and can install it on my hosting, please apply. My budget is around 5000-6000 Rubles. Only serious developers who understand Bux business models should apply
