Joomla Community Builder

Joomla Community Builder Site. ? I want a programmer who can build me a site with multiple communities. ? Ex.. I am a Business Student and I want to meet other business students, I log on to the website and fill out a profile. Once I fill out that profile it will direct me to the Business student side of the website. I will not ever come in contact with medical students or art students. ? I also want a creative programmer that will use their skills to suggest ways to interact with other people.
