An affiliate Membership Website creation with backend support and paypal subscription feature

I need someone who can meet my requirements. Basically i will be starting a membership site. So the first page will have a sales pitch (which I will write), and then at the bottom there will be a paypal subscribe button where people can subscribe by paying like say $ 30 / month. On payment, they will be provided with a unique login ID and password to access their member's panel. So all the members must have separate backend control panels. I ll be adding like 10 files per mnth which will show up in all the member's control panel section (note: file size would not be big, in few kb's:- its the product which i ll be selling). Personally i will also have an admin backend to add the files. The member control panel will have a tab to show their profile, feedback or suggestion, payment feature and a section to view the files that I LL BE ADDING MONTHLY. I need to launch this site by June 1st. I dont have big budget, but i need someone to do it good and fast. I have more work awaiting for the guy who bids the best. Thanks
