a photogrpher website

Hello coders , I'm a professional nature photogrpher? and I need a website to display and sell my pictures On Line. The website has to have a clean and neat design. The website must have as little flash as possible but has to be very impressive. The website's code has to be clear and maintainable. The site has to contain about 500 pictures and more. The site needs a PayPal code embaded so that the pictures can be sold. I need an easy panel to update the content and pictures. I'll need to get examples of other websites. Other apps will be needed. If the project is good, other s might also come...
