I don’t market to anyone now, besides the few people who find my websites it’s all referrals now and past repeat customers, with a handful of agents who refer me, but not many.
When I started doing commercial inspections I marketed heavily to Marcus & Millichap
Seems like that was all it took, I have been referred from one agent to another across the USA, now they have their clients call me once in a while, but most of the business is based on referrals from one customer to another and old clients buying more property.
I highly recommend contacting an office near you, give them a few sample reports in very professional looking binders with business cards and it might happen for you also.
Marcus & Millichap agents are very professional, I have never met an idiot who works for them yet.
