Here is a note from Entrepreneur magazine - a great article if you want to get into the consulting business:

Business consulting/staffing: Every business needs help sometimes--and that need is keeping business consulting and staffing franchises growing. In addition to nearly double the number of business consulting franchises, there is also a new emphasis on companies offering small-business and franchise-brokering/consulting services. Regarding staffing, we saw significant growth among the larger companies in 2006, and it looks as if franchises might be making a comeback in an industry they once dominated. “Some companies are making franchising a large part of their growth strategy,” says Richard Wahlquist, president and CEO of the American Staffing Association in Alexandria, Virginia. The Bureau of Labor Statistics predicts staffing services will be one of the fastest-growing industries over the next five to 10 years.
