ASP.NET Programmer for Making a Classifieds Website

Hello, I need a ASP.NET programmer for a classified website like OLX . Please do not waste my time by latter asking for higher amounts after you bid and don't bid uselessly for the sake of bidding. If you can do this job, send the links as samples of the ones you have created. What I need: 1. Not allow buyer or seller (user role) access to specific pages/ database on or during non-payment even after log in. 2. Provide access to user for the database only after successful credit card payment and only for a specific duration. 3. Removal of display of entries after a certain duration/ expiry 4. System E-mail to users on their updates, expressed interests, expiry, profile changes, etc (any account activity) 5. Provide one user role to have X number of contact requests for contacting the other party directly via website only during their paid period, (like freelancer gives X amount of available Bids in a month) 6. Their inbox for contact request replies/ messages after log in There will most probably be a few changes here and there on/ after finalization but above is the general idea of what I require. Please mention the time you will require and price.
