list of seizure service dog websites in west U.S.?

Does anyone have a list of seizure service dog website addresses in the U.S.?  I'm looking for a seizure alert dog, but also one that can protect me from strangers who might want to steal my purse while I am seizing. These dogs are extremely expensive $20K - $25K and have long waiting lists. (Over 1,500 people each.)

Thank you,
