The best salary surveys for your purpose will be available through MCPmag.com, because that magazine targets Microsoft professionals in particular and pays separate attention to developer credentials. Also check out the occasional reports from David Foote. If you can't find what you seek there, e-mail them and they may help you out anyway.
Editor's note: There is also a very good salary survey at SearchWin2000.com. If you click on "Create a report now!" you can see what an MCSD is worth in today's market.
