I need some changes to an existing website.

I am ready to start making some adjustment to our website, they are small changes to begin with but I will have more challenging request soon as we are adding new product lines to our collections. See attached CURENT website visual look as of now under: [login to view URL] I want the attached NEW website design instead. Each 4 images has been uploaded onto the back end of the website already in the proper dimensions but the program that is handling the site is reducing those images automatically so we need to manually override this. I would like it done as soon as possible. Thank you!
