Photo gallery e-commerce site re-design

I am looking for someone to re-build and simplify my current nature photography gallery website. [login to view URL] PLEASE look at the current site and read the details before responding. This must be something that I can easily update with new images and offers. Keep in mind that not only are there many different photos being offered but each comes in several sizes and can be ordered with or without frames. Important to note is that there are many frames to select from and that the shipping charges will vary depending on the photo size and if it's framed or not. I like the content and basic simple/clean look of my current site but it needs updating. The current shopping cart was added on to an older site so is not ideal. Redesign so as to make it easier to change items, pricing and features by adding more style sheets I'm guessing. Currently if I change the price of a photograph I have to enter that info in several places. The shopping cart can be switched if needed to run through Google check-out but currently it is setup for PayPal. I also use Quickbooks and if a checkout can be set up where this can easily be integrated into the check out that would be great and preferred. Additional updates and changes I need. *I’m working on a new logo but suggestions would be welcome. *The page which has a selection of videos can be changed to make it more user friendly. *New navigation needed... New "Video" page design.... New "Media" page design. Perhaps a “Comments” page could be added. *I offer Tours and lessons at times so having a “Menu Item” and page/s for that would be helpful. *Some of the Menu Items can be removed, like the “Links” tab and maybe other combined into a drop-down list. * I must have the ability to add coupon codes and easily remove shipping charges during special offers. I like the current layout as to how the different galleries (Penguins, Polar Bears, Mountains, etc... are set up and navigated. Over the years and with my very limited skills with Dreamweaver I've been changing the site, adding features, photos, videos, scripts, etc. Here are a few sites that I like the look of, at least parts of them.
