Small batch anodizing

Anyone out there know of a good place to go to get a few parts anodized? I have a couple of old seat posts that have seen better days - really scratched and beat, and would like to have them anodized black. I did a pretty good job of a repaint on one of them, only to find out it didn't fit in my frame anymore - bummer. Wondering if anyone (maybe one of our esteemed framebuilders) in OBRA-land has any recommendations? Bonus if the referral doesn't charge an an arm and a leg for setup costs? Reply off-list please - and thanks!
