Website developement

Hi, I would like to have a web page developed using postgres and php.
Eventually I would like to grow the web page to add a search functionality to it. But to start, all I would require would be...
A hope page with a little bit of info..
the ability to register and log in..
with each new registration, I would like a profile page for each new user to be created..
I would like all profile pages visible to the public (no need to be logged in)
the profile page to have the address .. www.examplewebpage/username
while logged in and on your own webpage, i would like the user to have the ability to add links..
each profile page will just be a header a list of their links in a nice design and a footer.....
I would also like to have the ability to "like or favourite" another profile and have a list on your own profile where you can see a list of your favourite pages... though this will only be visible to the user that owns the page....
I would like to have adsense
and the ability to log off..
is this in your scope of profession?
if so, could i get an approximate price
