Web development -- 2

I need a new website. I need you to design and build it. Website purpose is to realize real time video conversation, over the website module after a payment realization. DESIRED FUNCTIONALITIES: Main site: Main site with some introduction, very simple site, 3 main links with pictures. Login / signup option, maybe a YouTube video presentation. The web site can run on wordpress or similar redaction system. We will provide the space and page. Profiles: Profile creating and managing for trainer, the profile should include some text fields, like name, profile picture and some more pictures, text window for more information Profile creating and managing for customer, same as trainer, pictures, etc... Calendar: Trainer profile includes a calendar, where the trainer chooses when he is available for lectures. This calendar is accessible for the client, where he can reserve his lecture. Video-Streaming: The video streaming, where there needs to be voice and video, should be working for both sides (trainer and client), and also on main mobile platforms like iOs and Android. There is no mobile app needed (yet), but an optimized website. Video-streaming should be done using [login to view URL] module, or other simple module. Payment: The video streaming is only available for client after a payment realization, over an online method, like PayU, PayPal or other method using credit-cards. Administration: There should be an admin profile, which can edit every single thing on the site, approve created profiles, photos, etc. Price for this project Considering, that this may be solved by a Wordpress theme, adding the free plugin payment method and video streaming videolink2me, please offer me the final price without any further possibilities for reading the budget.
