I like Harry and he has done a lot for CA BBQ, but, I have to supply a different name or two.
I would contact:
Bart's Blazin' Q
Phat Matt's BBQ
Any of the three can do a good job with the meats. Of the three, Bart's is the one I know of that does more complete event planning. I hit Matt's at least once a week and his brisket is excellent.
I'm feeling bearish, and I'm packing a Wusthof Grand Brisket slicer from MABA
