My project is to develop a website where models, actors, photographers can register and post their ad/portfolio. My favorite site witch have the very same features I want and where you can get inspired is www.newfaces.com. You can get yourself registered there and get the idea. The PHP script must have the very same features, including front end, user end and admin. Design is not important, witch means, just for reference - I will provide the template.
