Convert a OsCommerce 2.2 modified website to a OsCommerce responsive website with theme

Hello, I have an ecommerce website based on OsCommerce v. 2.2. It now has a modified theme and, also, it has many addons installed and many extra-modifications. The website is this one: [login to view URL] (this is a live website, please do not create test accounts and do not place any test orders). Please check all the pages to see the differences between a standard OsCommerce 2.2 and this version. I want to buy this template: [login to view URL] and I need someone to install this template to my website. I will deal with the admin modifications myself. I will give you access only to the front end of the website. I need to install that theme and, also, make some minor modifications to it: - Add onmouseover pop for shopping cart; - Change the way that shopping cart looks like to match the way it looks now; - Implement a 1-page checkout (I will help with the programming part); Take your time to research on the way that OsCommerce works. There are many files that contain html style, so you will have to change a lot of files. There are a lot of functions and a lot of classes that include CSS and HTML code even if this shouldn't happend. Regards!
