Art Gallery - full image zoom - editable

Hi all, I am currently designing a website for an Art Gallery which requires certain functionalities beyond my expertise. Take a look at: [login to view URL] and you'll see the kind of functionality I'm after. The essentials are: Easy client administration and ability to add Artist pictures, descriptions and edit text and upload pics/artist info. Must be simple for non web savvy client. Full screen image zoom, see link above for examples - but other ideas can be discussed. Print format page. Search facility. Plus other standard functions such as contact form etc which can be discussed later. I would provide you with Illustrator files for the design, see the work in progress (just click in middle of pages to go to next page) below: [login to view URL] There would be NO shopping cart though. I will also provide the hosting of the site too - Linux, Windows or Unix. I'd also need to know that if any future problems occurred you'd be able to sort them out. I'm not sure how much of a job it is for you experts so I've put it in the Medium Budget Range. Regards, Steve
