Need A Simple Website that can perfom the following task efficiently

The Website will be for a club that accepts members to join online based on satisfying registration Conditions. Registration Conditions will include the following; (1). Agree with terms and Conditions. (2) Fill Registration form with required information. (3) Make Payments to all Listed Accounts on the site. (4) Confirm Age eligibility. There should a SCRIPT or CODE to confirm that all conditions have been met. All new members will join from an existing member site. After completing registration requirement, a copy of the site should be created automatically for the new member with the new members USERNAME as a third level Subdomains E.g Let us assume the main site web address is : www. [login to view URL], and Let us assume the members site on which new member is joining has this address; [login to view URL] , the new members username is "good44", the new member web address should change to : [login to view URL] No Two USERNAME must be accepted, that means there should be a database of existing user name to confirm availability of the username before it will be acceptable on the site. MEMBERS WEBSITE SIZE ECONOMY. Some pages will not be replicated, but resides on the main website, and there will be links on members site to view them. Main website will not be open to members, but will be covered with an information page asking viewer to register through an existing member. EXISTING MEMBERS PAYMENT LIST ON A DYNAMIC TABLE TO BE ROTATED TO INCLUDE NEW MEMBER ON ITS OWN SITE. An Ordered list of existing members will be on a table showing, Username and Payment Button. The Payment Button will be linked to Local Bank Account Information. New member joining will pay each of the SEVEN on the list the same amount and pay two other static list not numbered. The existing member table will change when the new members website is to be created with their own username fixing the new member on number-7, while all other people will move-up by one and number one on the list will be removed. For example: Let us assume there are 7 payment links on the list, after all payment has been made and payment confirmed, and a new member site is to be created the new table should be arranged like this; ; no 1 will move out, no 2 will move to no 1, no 3 will move to no 2, no 4 will move to no 3 no 5 will move to no 4, no 6 will move to no 5, no 7 will move to no 6 AND new member to enter 7 BACK OFFICE. A password login protected back office where members only should be able to see their downline Gyneology and other special Resources for members only will also be required. The Gyneology required is just a list of downlne on generation by generation basis, not necessarily the complex MLM gyneology tree. Since there is no commision to calculated, payments will be made directly to members.. PAYMENT PROCESSOR API. No need for any third party payment PROCESSOR, since no third party will be engaged. E-MAIL and Phone Number DATABASE. which will be used to send bulk e-mail to all members and if necessary send bulk SMS to members. TEXT PAGES There will be few text pages to give out necessary explanation of the program concept, vision and Mission. ADMINISTRATOR Access. The administrator should be able to edit pages with WYSIWYG content and Drag and drop contents. And should also be able to change some parameters in the codes or scripts if necessary. There should also be a link to disable any erring members site for some reasons. MORE INFO On PRIVATE DISCUSSIONS if necessary. Thanks. .
