Possible to incorporate Elance (freelance tool) onto wordpress

Hello all,
I am working on a project that allow users to sign onto my site without exposing WordPress. There they can submit application for the public to see. Similar to Elance where both freelancers can post their qualifications for employers to see. Are there any known plugins out there that allows me to do this?

Additional features is that they can submit a profile picture and brief description.

Any help is widely appreciated, thank you very much.
