You can find relevant hunters for your niche here: https://upvote-bell.com/leaderboard
The best is then to contact hunter on Twitter or Linkedin.

By contacting hunters and asking them if they would be interested. Fabian's link is going to help you pick people from a relevant industry.
However, a popular hunter isn't a guarantee of success, unfortunately
