Add Paid Members With Secure Access

I posted this project last week and had a guy say he would do it and have not heard back since si it's up again. I need this completed by 11/25/04. Looking to add to a web site the following: People should be able to log in to a area of an existing web site and to Purchase Service which will allow those who have paid for service to access a secure page. Payment will be processed by Paypal. The area should be set up so that once a person pays the payment is verified and approved by paypal and they the client will get access to the secured page which I can upload from a simple control panel using a html program. The client will pay for membership based what they pay for i.e. if they pay for 30 days they are allowed access for 30 days, if the pay for 1 day they get 1 day, if the pay for say 5 uses they can access the secured page for 5 uses anytime they want. I have seen programs in a box for $75.00 uploaded and looking for something less and uploaded. Send questions to swapperworld @ aol
