As of right now there are two companies I feel safe sending my anodizing work to. If it's a more elaborate splash or acid wash I would go with Anotech Metal Finishing and I you would like a type III finish I would suggest Arnold's Metal Finishing. If you're somewhere simple and type II either should work. PK Selective was on my list but their priced for small batch work simply aren't competitive.
ps. if you need any help making a wiring harness let me know.
