Company recruiters for CMGs are paid by the company and are figured into the overall amount of money the CMG skims off your RVUs if you go to work for the CMG. As such, you're not going to lose a signing bonus by talking with them since it's expected that pretty much any doc that lands with the CMG is going to have gone through that region's recruiter. Most CMG will actually pay non-recruiters physicians who refer a doc that signs a contract but these tend to be significantly smaller (<$5k) payments than what freelance recruiters get.
