I am trying to get a better general understanding of College Matching
Professional Services and their usage by potential college applicants.

For the asking price of this question, this is what I would be
interested in knowing:

- Price range of their services
- General description of their services: duration of service,
offerings, medium used to deliver service (one on one only or internet
based too)
- Aproximate potential college students nationwide that hire their
services  (it can be a very, very rough estimate as long as any
assumptions are presented)
- Website Links of 5 professional college matching services

Thanks!
