CRE Loaded installed in my OsCommerce Store

Re-posted becasue the original budget was set too low for this project. I would like CRE Loaded adding to my already modified quite a bit OsCommerce store. Without breaking the current installation at all. I need someone who know's OsCommerce inside out and who is very compitent at instlling contributions. You will need to be a good communicator in English and will need to do a full back up before doing any modifications. I have had specialist scripts written to handle the currencies etc and need to have everything working when complete as it did before with all of the added stuff that is in CRE loaded. I have downloaded the latest version and can let you have it to install. I want the whole thing to work just as mine does now. If this is not possible then someone please let me know. Please take a look at my site [login to view URL] to see how it functions now.
