I'm trying to help a client determine the attractiveness of the Texas
market.  The company is an executive search firm new to the Houston
area.  I need to know (if possible, information for Texas and
specifically Houston):

1) List of executive search firms doing business in the market
2) Industries served by each firm
3) Average retained search fee
4) Number of placements per year
5) Number of employees for each firm

I realize that you can't provide me with a complete competitive
profile, so pointing me to the resources with such information will
satisfy my question, as along as it's complete.  At this point, I'm
trying to determine whether this information is easily obtained or not
before I begin the project.

Thanks.
