CRE 1.5 Complete Secure https of website

My website is at [login to view URL] I need to have the secure portion of the site (httpsdocs) completed. The webhost does not support CRE only basic Oscommerce. One problem was warnings due to the host shared SSL. when going from http to https. The host, globat installed a fully operation oscommerce on my site at [login to view URL] to prove that it can be done without any warning. I already have the merchant account approvals [login to view URL] and will need to complete and test the payment gateways. There will be a second job later: I have 300 products on my site from one company and will be getting 200 more from another soon to add to the site using easy populate, already installed. Requirement: Need someone with Good communication skills as well as technical skill. Thanks. John G.
