Web Site Upgrade Integration

I am looking for someone or a team to integrate my website update to the software I am using called opentaps. Please look into the software to make sure you can handle this kind of work, the site is [login to view URL] We are running on a linux server right now. The goals are simple: 1. update the software using instructions from opentaps from 1.03 to current version. make sure start up script is intact and new upgrade works with the psql db we are using. this should be pretty easy. so, a backup of the 1.03 we are using and everything that might be jeopardized from the new install. then download the latest version and change it over to our server. we may need to delete demo products. 2. integrate the splash page retail site upgrade we have had done already with the opentaps software we are using. this includes plugging in the links of the products we are selling so that someone buying from the site can simply buy and move through the site comfortably. management section will not be needing work. 3. install certificate of authority from godaddy. c o m 4. integrate credit card authority or authorize.n e t so people can order and pay by credit card. the code is all completely written in this software. I am looking for someone who has done this already or is very familiar with opentaps. I have worked extensively with it and know it can go smooth and easy.
