I have posted this project before, but now increased the budget.
I have a script similar to sobftbiz freelance script in PHP. It is unfortunately missing lots of features which the [url removed, login to view] script already has. Following you will find a list of these features.
I would require following additional features/modifications:
-) adding an Escrow system similar to [url removed, login to view]
-) adding a private message system with look and feel like GAF including the ability to upload files similar to GAF
-) ability to upload a file when posting a project
-) ability to hide the biddings from other users simliar to GAF
-) no separation btw/ webmaster and programmer as users (my current script makes this separation from the sign up process)
-) including latest won/lost biddings in the review ratings similar to GAF
-) Including bronze/golden memberships
-) including featured/non-public project properties similar to GAF.
-) some other small modifications. You are welcome to offer new practical features.
Service providers with experience in similar freelancer projects will be preferred. Please provide reference.
Lowest quality bid will win.
