I had my already-stripped frame powdercoated for $75 a couple of years ago. That was for the main frame and the fork, two color coats and a clear coat. Having them strip it would have upped the price to $90, and considering what I went through to strip the old paint, I should have bitten at that deal! Unless you're looking for some fancy effects, powdercoating is the way to go - it's much more durable than paint. You said your frame is Chromoly, but if it were aluminum you'd have to make sure they used low-temp powdercoat so as not to ruin the temper.
