CSS Sprites, Googlemap using ajax, text box with line number

There are three tasks that need to be completed on this project: 1. Convert 7 pages to css sprites 2. Modify a form so that when a user types their address in, the google map on the page will automatically locate the address on the map. 3. Provide textboxes on a form which will have line numbers. I will provide more details to the prospective bidders. I need to see examples of your work which includes using css sprites, work which utilizes ajax and I need to be convinced that the text box can be done and that you can do it. What ever you do on the site needs to be in line with xhtml strict, must validate with the w3c, must work on the following browsers: ie6,7,8 and ff3+ and safari 4+ and opera 9+. The site uses the mootools library. So if you do anything that requires a js library, let me know if you can do it with mootools. If you are not able to do everything in this project, then specify what you can do and we will work out a payout for that aspect. This project will require the following skills: css/xhtml, using css sprites, ajax and javascript.
