Install & modify a number of add-ons and cosmetic changes to existing Oscommerce 2.3.3 site

We run an online store (in development) using Osc 2.3.3 and wish to install some pre-written add-ons from the Oscommerce site as well as make some modifications to the site. Some add-ons will need to be modified/re-coded to work in conjunction with our modified site and or from being add-ons created for Osc2.2. Full details of the changes required are attached. We need a talented coder to edit the code and install the add-on's onto our test server. The coder should have a little design flair as we need them to modify the contributions so the colours and look are in-keeping with our site. Full development site access details etc will be provided to the winning bid
