None of the ones that I know specialize in racial placements.

What you need is a competant head hunter who will place you for your skills.
Depending on your experience and what you want to do (work for a user in a specific vertical, vendor or consultancy) there are several specialist head hunters. Then there are some exclusive ones.. which, if you have to ask, you don't qualify.

They seem to do a fair amount of work and have placed a couple of people I know, in fairly senior positions.
