We need to have compiled a list of several technology staffing and/or
recruitment firms in Texas, preferably the Dallas area.  Information
requested (if available) for each firm includes the name of the firm,
the URL, the phone number, and the primary contact person.  Thanks in
advance for your good work.  A bonus equal to the value of this
question will be given for a high quality answer.

This might be of some use:
