Website creator

I would like a website created where users are able to create their own website within the main site. I want it so they are able to create professional sites and a click, drag, and drop method. No coding will be needed for users to know to create there own site. I wants the sites that they create to be on a HTML code and not Flash. How it works: 1. User signs up and after sign up they are directed to a page with two options. 7 day free trail Or Membership The 7 day free trail will give members all features only for 7 days so they can see what it's like. Once there seven days is over and they try to create or edit their site it will tell them that they have to buy a membership. If somebody presses Membership it will direct them to a page with three options. How would you like to pay? Monthly - $8.99 Yearly - $ 120.00 Lifetime - $500.00 And they will be able to pay Via PAYPAL Once they have purchased a membership there account will unlock all features and they will have the sites until they cancel thier membership. I will also need you to make sure this is good. Once the purchase thier membership or in thier account options have an option that says connect a domain. When a user presses connect a domain, it will then bring them to a page where it will tell them the name servers that they will need to enter into thier domain registrant. Please make name servers for this site so it works when people type the users domain name and it goes to thier website that they built with my website but its on thier domain name. You will also need to make over 50 templates from users can choose from, and once they choose one they can edit thier site with that layout. Besides the templates there will also be a basic template which has nothing on it. Thanks. I'm looking for bids around $100.
