Content driven site

Hey,
Basically, I just want a price on how much it would take to develop my web page.

This is what I am hoping to have done:
1. Users each have a front end and a back-end to their profile, this means back-end would be where they are told they have a new pm, what friends they have, etc. and the front end would be whatever they wanted it to be.

2. Each content developer has their own page that they can edit, but all the content they have on one page is put into an "archive" that has all of then content, where you can sort by developer, date added etc.

3. Integration of Wordpress.

There may be some other stuff, but for this how much would it cost?

Thanks!
