Could you recommend a software application (preferably open source)
that would allow subscribers to a site to log in and have their own page that is on the same format of the main site but allow them to upload images and receive reviews on their services?

try Buddypress or ning.com

Buddypress looks quite cool.

There was one that I was thinking of buying some time ago. I can't remember for the life of me what it was called. But it's features were amazing. Was expensive though!

something like Deviant Art or that type of site?

I have seen a couple around I will take a peek to see if I can find one for you.
