I can think of a few that I know make CZ holsters.
TT Gunleather TT GunLeather High Quality Leather Gun Holsters
HBE Leather H.B.E. Specialty LeatherWorks
would both be good places to look
Also, Eric Hopp would be worth finding out if he can make you something http://www.facebook.com/HoppCustomLeathers
I'm sure there are a number of others, but there's a place to start anyway.
