'Search For You Programs' - any experience, recommendations, etc.?

Curious if anyone has leveraged a 'Search For You' program from any M&A Firms or business brokers, others ... or if anyone has any recommendations for services that do off market and on market searches for part time self funded searchers.

I looked into this one from Bison Business (redacted) ... but if anyone has any other recommendations or experiences with this sort of service, would welcome feedback.
