Create website/system similar to lifeat.com

I would like a site built similar to [login to view URL] some similar features some different. Key elements are that every estate will have its own admin user to manage users , and different sections as layed out in the spec sheet. Please see attached spec sheet + ppt of front end to get a clear picture. Also i a leader website that is different to the community sites is needed , in the same way that lifeat does it. Due to size contraints low res images have been loaded . I will send high res to the successful bidder. Please not that this IS NOT a static site but an interactive site for communities to facilitate various functions.
