Commercial website/mobile application creation - repost

I need a website designed with video chat capabilities. The site needs to look extremely professional as this is an e-commerce site. I will need three different areas for the site: for customers, employees (independent contractors), and administration. I will need a mobile application developed for the customers and for the employees. My employees will set their on call times and should be able to be notified via the mobile application when a client books an appointment. I will be providing one free session to my prospective clients so I will need an IPS address recorder to ensure that customers do not use this function continuously. Each of my employees will have their own profile and I will need a search function that will basically be a matchmaking service. All video sessions will be archived for one month for each client. These are the basic functions of the site. It will probably be somewhere between 30-50 pages when it is completed. Please contact me for more specific instructions. Thank you.
