OsCommerce add ons etc

Hi, We are starting a site but need a few add ons done - our current site can be viewed at [login to view URL] this is a test site etc. What we require is the following - Need Tabbed product info descriptions - Install FCKeditor - Install Ultimate SEO add-on - latest or best? - Install one page checkout - Add a Manufacturer section in the left hand info boxes underneath the Categories section. Basic stuff mostly but i do not have the time at the moment. Will make available source codes and access to the hosting environment etc to winning bidder Cheers Riaan
