URGENT: CATEGORY ON OS-COMMERCE

We are fashion e-tailers. We have an os-commerce (version '97) modified. Currently in the navigation bar (on the left of the pages) customers can view the “search by brand” but not the “serch by category”. We need urgently a person (experience: oscommerce and php) that find the way for to have at the same time "serch by brand" and "serch by category" on the navigation bar. We also want add the button "Share & Bookmark" in the product pages. It's an ordinary past and copy, but we need the button in an exact place of the page. This is a really simple job for someone with experience in os-commerce and php. But we need it as fast as possible (naturally it's required a test before go live the changes). THE STORE MUST LOOK PERFECT AFTER CHANGES (everything must appear exactly as define). We will pay when the job go live and only if the job will be perfect.
