Membership website PHP/SQL design

Here is the basics: User comes to the homepage, there is a login form, some introductions and a link to registration page. User register and create their profile (upload picture) for free. Once they login, they can modify their profile(with picture), or choose to upgrade to premium membership which requires a subscription payment (Paypal). Free member has limited search for other members.(limited search result and can't view other members' contact info). Premium member can do full search and can view other members' contact information. Admin can manage members and send weekly newsletters from admin area. We will need your work on designing the layout/graphic of the site too. We want it to be a clean and nice looking site with clear messages. Above listed are the features we want to have. There will be details and tweaks, so we would like to have someone work on Skype so we can chat and communicate while you work. Please give bid price and time frame, sample sites you have worked on before. Thanks.
