Website Update

Update of existing website. The purpose of the business is to put people in touch with a language tutor so that they can improve/learn a new language. I am trying to transition the business from a website which directs people to calling or emailing us as an intermediary to one where the customer can book a tutor directly over the website. An example of a company who are already doing this is Tutora. I have two websites at the moment http://galaxylanguagesolutions.com/ and http://www.galaxyonlinelessons.com/. I would like to change one of these sites to allow tutors to upload their own picture, a biography, levels of experience and specialism. Once the profile has been approved by the company it will go live. These profiles would then be displayed on the site enabling customers to searh for a tutor near to their location using a search facility. Alternatively they could book online classes with a tutor over Skype. The tutor would be able to set their hourly rate and the customer can either book a trial lesson or groups of 5 or 10. However, many they like. Each time a booking is made Galaxy would take an introducer fee (to be determined). Hope to get some good advice on how this could be achieved. Thanks!
