fix some bugs in oscommerce website

I'm looking for a service provider who can fix the following bugs in an oscommerce site: add code so old sub category are 404 not found in header modify category menu, click to drop down, click to close (expand/collapse) when a review is added, then another review is added by a different user, the review date is the same as the other review on [login to view URL], even if i change the date in the database The % would recommend to a friend (0 of 1) isnt working, I have recommend this but it still says 0 in the product summary Not saving review helpful Add code so the feedback review stars show under the product name on index, sub cats index and we also recommend in [login to view URL] change position of price from below buy now button to above buy now button on [login to view URL] change position main product image opens to in [login to view URL] quick updates not working in admin, when you click to change the number of lines per page or try to make lowest price first it just refreshes the page fix product search - it is not finding many items add item to cart adds amp; to url when you continue shopping, it takes user to product not found instead of back to product page These bugs will be easy work for anybody who is good with php and oscommerce. the review system uses some ajax, i dont know if that is the problem but it would be good if you also knew ajax. I will pay up to $50 to have the bugs listed above fixed. The project will be awarded to the service provider who can complete the job in the least time and budget.
