create nav menu using jquery &css

Hello, I am looking for experince designer with strong knowlage in jquery & css to create navigator menu using jquery and css. You can see what we did at: [login to view URL] The new script should used the <ul></li> structure as in the file: [login to view URL] you can add id, class in the items(ul,li), DON'T change the items (ul,li) structures. The script also have to show the active cat, and the active sub cat: 1. Active cat with blue backgroud - as the mouse over. 2. Active sub cat with white backgroud - as the mouse over. You can create 2-5 test pages to test the script (active cat & sub cat). The menu must be fast, andHTML & CSS valid and very simple. Our budget is 40$. Regards, Sam
