Designer with knowledge of Less CSS/Java/Twitter Bootstrap required

Hi I have with me a gradient+color generator in Java script. Separately I have a Twitter Bootstrap template with me that has many pages. What I wish you to do, is create a web app for me that asks the user to select an element in the Bootstrap template, then use the gradient/color generator to generate the CSS for that element, and show the updated template immediately. Also, the CSS is to be generated using Less CSS--> this has to be done using java code which will basically send the relevant less CSS variables to the backend server and using Java code the CSS variables will be used to generate the actual CSS. In this manner, a user should be able to generate a completely new customised template. Some sections where CSS cannot be used and images have to be used--> here there will be multiple folders in the server corresponding to each such section--> and your app has to pick up all elements in one folder (corresponding to one such section) and show them to user--> now user selects whichever image he wants to be used for that section, and finally that image is selected, and relevant CSS code for that section (which uses the image selected by user) is sent to server and the template is immediately updated with the new image. There are many (more than 20 pages) in the twitter bootstrap template that I have with me--> and you have to create a template generator for each page. Actually most of the CSS elements are same across all pages so work is not much--> only thing is I need a separate template generator for each page in my template. I already have the gradient+color generator with me, as well as the Twitter Bootstrap template. These are attached with this project. Do let me know if you have any queries, Yours sincerely, Arvind.
