I need Designers Wordpress site

I now need a multi-functional website including: classifieds, dating, community and news. Once a customer creates an account and uses it for all the features such as posting ads, joining forums, chat rooms, making friends, and commenting on news ... And of course there is no shortage of features. Membership level to apply fee according to different levels as well as payment gateways such as: Paypal, Stripe ... I do not currently have a template to send to you. But I can tell you that my idea could include as the sample below and once the customer registers once for all. 1 / [login to view URL] 2 / [login to view URL] 3 / [login to view URL] As I mentioned above, for features such as dating, communities, classifieds ... included in the three web sites there are many duplicate features, we should dump things already exist. The key here is how we can set up a one-time registration function and use it for all features: dating, community, classifieds, and even billing. Please advise me a reasonable price if possible as soon as possible. I can make a proposal of $ 500 to 1000.
