Progress bar image rendering in Javascript

This project is straightforward. I have two images, one a base and the other a snippet of the progress indicator within the base. I need javascript code that can be dropped into an existing web page to display the progress toward a fundraising goal. The developer will create the javascript that queries the server for a static file of information to use to calculate how much indicator to display and what/how many labels to display under the progress bar. Deliverables: javascript file to preload the images, query the server, calculate the progress, manipulate the image, add the labels using markup, and populate the div, whose id will be passed. Stylesheet used to control format/layout of labels. See attached PDF for more information. ***Edited to add*** If you wish to submit a bid using a server side solution, you may do so using perl or PHP. Just design it using a flat file of your format choosing to provide the data. The data will be maintained by another process.
