Set Up Zen Shopping Cart w/ Custom Look

Greetings! I have created a website and would like ti now create a shopping cart. I have loaded Zen cart. I have started building my shopping cart. I'm looking for someone to stear me in the right direction so I can complete this in the next couple of days. Someone who is an expert in Zen Cart customization. So Please don't bid unless you are an expert and have time available starting today or tomorrow. As far as catagories and products, I only have two dozen or so items to enter. Pretty simple stuff. Half of them I've entered already. I've budgeted $100 max for phone technical support depending on the amount of time. I figure $15 -$25/ hour would be fair. Basically, I know how to edit HTML files and know how to use Dreamweaver. I just need to know which files I need to modify to give my cart a custom look, specifically: What I want to do is get rid of [login to view URL] and [login to view URL] Zen cart header images and put my header image (logo). Then I want to change that rust/orange color [login to view URL] that accents catagories, information,etc. to match my new logo color. Once I find the files to modify I will download them to Dreamweaver and make my changes. I just don't know which files these are and where they reside ? I was looking for an [login to view URL] file and I found many of them in different folders. Plus I did not find one that had a recent modification date to reflect the changes that I had made yesterday when I built the cart? Also I'm not sure if I'm supposed to modify this [login to view URL] file or the template ? Thanks! Kevin
