Quoted from dgpinball:
Wish I lived in your neighborhood, went to a local powdercoater for a quote, they told me at least $250 just for the setup charge!!
Find a new guy to do your powder coating!!!! He's ripping you off. I had the entire metal frame from my 4 Million BC powder coated including all metal trim and he even powder coated the nuts and bolts for $100.00 total! Yes, he worked it in between production jobs and it took five weeks to get back but the price was right and the work was outstanding.
