Do your research on the forums for general tips on hiring a PM, what to look for, what to look out for, good stories, bad stories, learn from others about their experiences with all kinds of PMs all over the place and take what you learn when you're speaking to PMs in your area so you can more easily see red flags, or green flags!

it's not necessarily a red flag - it's because there is so much demand right now that they can pick who they work with.so... it's just tough =) Yeah, this goes both ways.
