Modify existing osCommerce website

Greetings, I am looking for an individual with a good set of PHP / JavaScript skills to help me modify my existing website which is built with osCommerce. Currently I am renovating my website and I am experience some problems with editing particular sets of code. At the moment I would like to edit the view of my drop-down menus. Here are some examples: This is my current view, which is fullwidth and unorganized: [login to view URL] I would like it list from top to down like the following example: [login to view URL] That's why I need someone who is confident and knows how osCommerce works, how to code in PHP and JavaScript. If the job will be completed fast and correctly without any problems I have a lot more little jobs to do in the future! Please write the result of 2+2 when applying for this job.
