Project Description:
Hey Freelancers,

I require a website that is kind of a refer and earn. Nothing fancy and nothing extra in it.

When some one joins a website, he/she pays a set amount and then he/she is given an affiliate link which upon promotion and successful referral, the promoter receives half of the amount of signup every time.

I need a simple script for this task - If you can do it then bid for it.

Any questions or clarification required before quoting, do let me know.

Skills required:
eCommerce, MySQL, PHP, Software Architecture, Website Design
