Try Capt. Dave with Blue Water Adventures. He has worked with Tech divers before. He runs a 6 pack Cat Hull boat located at the fish house. Great guy and great Capt. You can also get his info from Dive Pros on hwy 98.
Just about any of the local dive charters will run tech trips, and are pretty easy to get along with. I don't think Capt. Dave on the Y-Knot is working with Dive Pros any more. I know you can now book him through Scuba Shack. Dalton Kennedy is another great choice if you're looking for a six-pack. Doug Hammock on the H2O Below is great with Techdivers and can run larger groups.
