I have with me a gradient generator that generates the CSS/JS for any gradient as selected by user through a color/gradient picker.
Also I have with me a twitter bootstrap based HTML/CSS template.
What I want you to do is, create a simple JS app that allows the user to choose a gradient (using my color/gradient picker) for different elements of the bootstrap template--> and then your js app generates the necessary css/js code for that element of the bootstrap template.
Some elements need images (not gradients)--> for those elements a simple image selector is shown and the user selects an image, which can then be used either directly, or with repeat-x and/or repeat-y for that element in the bootstrap template. And your js app generates the CSS necessary to use the user's image for that element in the bootstrap template. Finally using Jquery+oauth your app should post generated css/js code and selected images, for the entire twitter bootstrap template to REST API.
Since the basic gradient generator is already there with me, this work is pretty [url removed, login to view] I expect low bids.
