Zen commerce edit to my specification

Hello, I just installed a Zen ecommerce site as a Sub on my main site I used the automatic install from my hosts Fantastico. I need someone to do some lite alterations to the site or script. One example would be to add an option to the products to have more than one price option for example 1 piece is $???.??, 6 pieces is $???.?? and so on it would be added to the cart. Another option to product would be I can add multiple pictures of the same product. I want to keep it simple and delete and add some things along with some style alterations. Here are one or two sites that I like how they look and are set up in a simple style one is [login to view URL] another is [login to view URL] I can buy these sites already made for a very low price but will still need to alter the above two things I mentioned the price and picture options. I would like to also be able to ask you a few things to how to alter or customize the options using the backend admin features of the Zen script. Please ask questions before giving any bids so I can give more details on what I need I would like to keep it simple I have a very low budget. Thanks.
