Add e-commerce to photo gallery site

This job was posted earlier in the week but was limited to "Gold Members". If you would like to bid please reply with details on THIS project, how you would set up the e-commerce and if possible include samples you've completed pertaining to e-commerce, especially any that are for galleries selling art. If you've already placed a bid I still have those and am still considering them. >>> I have a nature photography website which I like the layout of but now I would like to include e-commerce. [login to view URL] Each photo is available in several sizes and may be purchased unframed or framed. I have over 70 different frame options broken down into 4 price categories. I've been looking at Zen Cart as a possible option but am open to suggestions, especially those that would somehow work into my current site. I'd rather not have to do a complete re-make of my site. The current script for displaying the images in different "galleries" was purchased from Project Seven and is called Image Gallery Magic. Here's a link. [login to view URL] They told me that many photographers have used it with a shopping cart feature. I also want to be able to update the images/site myself. I've just moved the hosting of the site to InMotion and have the "Power" hosting service. [login to view URL] For my brick and mortar store I use ChasePaymentech for my credit card procesing but am open to suggestions...PayPal, etc. I'm looking for suggestions, and of course price is a consideration. I tried e-commerce on my site over 8 years ago with little luck so am taking a conservative approach to this now. The site was completely different at that time, and times have changed, I hope. +
