Oscommerce Addons install and some fixes.

I only need a few more things so that I can start finalizing my website. Here is a few addons I still need to my website. 1) JQUERY / AJAX Advanced Order Handler for Oscommerce 2.3.3 - Need full installation. 2) One Page Checkout - Need full installation with the complete [login to view URL] file. 3) Shipping: a) Need to install the DHL Shipping package. I got the full integrated DHL XML-PI Services Toolkit. b) Install a shipping addon - shipping quote in cart. c) Together with the above addon I need to offer free shipping and flat rate. Then I need some small changes and fixes on stuff that is already on my website. 1) A.A.S (Alternative Administration System) - I installed it successfully but the unique ID must be set in the [login to view URL] to be able to preview the product description in the A.A.S system on the admin area. 2) What's New - I want to link the Build your Perfect PC into the what's new module. Also the what's new must be changed to Custom Build PC. 3) Product Listings - Remove the "model" from the top right bar. 4) CCC - Custom Build PC addon - Need some small fixes that is not working correctly on this specific addon. 5) The We Accept payment logo's right at the bottom of the page I want it to be configured that is show in the footer box. Maybe we can make the footer box the whole width of the website with the grey color right through. 6) The testimonials addon also need some small fixes that is not working correctly. 7) I also need a small change of showing different kind of products in the product listings. All the same kind of products is showing that I added last. Can that be done or do we need to install a addon for that? I need this to be finished asap. Thank you
