3 dynamic pages

Website design is already underway. Once that is delivered, I need a coder to make the three product pages dynamic. The product pages are just a table of thumbnail images (example - [login to view URL]). Any anonymous user may view them. Users who sign up with their contact details (and are approved) will see the same three product pages, but those product pages will also display the prices of the product below each thumbnail. Please let me know for how much you can do this, what technology/language you propose to use, and how long it will take. If you have done something similar, please send me a link to your server. I will expect to see a working demo on your server before transferring ANY money.
