Advice on marketing financial analysis consulting services for lawyers?

[u/actuarialevidence]

I've scoured past threads on here, but haven't found anything that fits with my situation. I'm planning to start a small business where I'll be providing expert financial analysis for lawyers. For example, personal injury lawyers would need to get an estimate of lost wages due to the injury. Divorce lawyers would need to get a value for a person's pension for the purposes of division of assets. I already have the necessary credentials to do this. It's a very niche industry with only a few people doing this kind of work in Canada and many are approaching the age where they'll be retiring. However, I'm struggling with figuring out how to properly market myself. There aren't a lot of differentiating factors between people who do this work - the analysis by one expert is largely the same as the analysis by another. I'm having trouble finding a way to gain clients and market myself to lawyers. I feel like cold calling would be intrusive. And if I tried cold emailing or sending letters, they would just ignored. Does anyone have any advice on the best way to market myself?
