OsCommerce Mods

Im looking for someone with experience in OSCommerce & PHP to edit my oscommerce template based store - Essentially I need to have category Images (image headers) inserted in the header of each category page instead of the defualt category words, also need a couple of layout fix's on the Category/Subcategory pages. Please let me know if you need any more information to bid. This is not a big job and I ideally need someone who has worked on OSCommerce before.
