PSD to HTML for a facebook app

Hello, Our company creates social games. We've already got two products using roughly the same layout. This contract is about the third one. The website are developed using Python/Django (though there should be zero modification on this part of the code), LessCSS ([login to view URL]) and Javascript (using jQuery). The point here is to implement the new design upon our canvas. This basically means : - using the given sprite sheet (png file + css file) - changing colors and fonts in the main stylesheet - changing some elements' positions and dimensions There are 3 pages + a dozen of popups (which are all slight variations around two base ones) How we proceed : - you set up a paid-for github account (we will pay one 7$ month fee) and fork the projet we'll give you credentials to in a *private* repository - when you're done you submit a pull request, which we'll merge with our project.
