Basic Website design - Save favorites & create Tabs

I would like to have a basic website with: 1. Admin Management 2. User Accounts 3. Site Search with radio button to search for Favorite Tabs or Favorite Links or All (Tabs & Links) 4. Join/Sign-up Page 5. About Us Page 6. Quick Tour Page 7. Help & Support (link to email) 8. Terms of use Page 9. Privacy Policy Page 10. Total Tab Counter Admin: 1. Allow Admin to (Mass) Manage User Accounts. (Add, Block, Delete) 2. Allow Admin to Create/Edit/Delete Tabs. 3. Allow Admin to turn off site for updates/construction. 4. Allow Admin to edit Pages: (About Us Page, Quick Tour Page, Terms of use Page, Privacy Policy Page) Users: 1. Allow users to create Accounts with email verify. 2. Allow users to Create, Save & Share Tabs. 3. Allow users to Name, Rename & Remove Tabs from their accounts. 4. Allow users to move Tab order with drag-n-drop feature. 5. Allow users to search/Add Tabs to their accounts. 6. Forgot Account Password (Retrieval). I would also like the site to look like the design I have attached. I would like the site to load fast, & allow many users to use the site at the same time. I am not sure what program to write the script in. This will be the start of an ongoing project. I am looking for a company who would like to complete future site upgrades.
