Some bug fixes & minor enhancements to a custom oscommerce mod

I need some bug fixes to a custom oscommerce modification urgently. The bugs fixes are things like there is a colour selector for a background in the products page that needs to change the colour of the background as selected from a drop down list, the code used to work and now it doesnt so it's probably something simple. Also there was a drop down list that when selected it would switch products displayed, once again it no longer functions and goes to an error page not found as does the above issue. In the same page there is a another minor bug where the attributes of a product show with comments (set in admin) and all but the first attribute's comments show. I'd like to have the first attributes comments appear too. And a couple of other minor things like that. This project is urgent so I will select someone qualified pretty quick and need it done within 24hours of the job being allocated.
