Greetings,
When providing estimations based on an example of a similar product, there is always some risk of misunderstanding, because the buyer and the developer see the same features from different points of view. This is why we would like you to provide an exact list of functionality you need to have in your project, even if you have an example that is very close to what you are planning to achieve.
Please pay attention to Wink Wink Adult Social Network project in our portfolio: It is a very sophisticated social network for adults, swingers, minorities, etc. Has all the bells and whistles of a social network, including chat, personal messages, profile images and videos, blogs, forums, video chat, events, photo contests, content moderation, spam notifications, promo codes, paid membership, sub-administrator accounts, newsletter and even a special admin area for clubs to allow them adding their events.
We are also currently finishing up an adult amateur video and photo website with multiple account types and paid membership.
We will create a customized, turnkey system for you, which will be ready-to-use upon project completion.
Considering the above information we would like you to pay attention to our portfolio at: http://www.freelancer.com/u/devexpertsteam.html.
We would be glad to answer any of your questions and provide with further assistance.
Sincerely,
Andrei
