Local colleges sound like a great place to look. Especially if you’re able to have kinesiology professors connect you with students they’d recommend.
Have you conducted a simple Google search for “personal trainers” in your area?
-With this information you could reach out directly to the ones that fit the characteristics you were looking for.
Hope this helps and best of luck to you in your search!
You can also try the websites of certifying organizations.
For example, ACSM has ProFinder. I believe NSCA does as well, though I can’t speak for anyone else.
Also try searching as an employer on Indeed, Monster, GymJobs, and other job boards.
Not a lot of facilities themselves will offer it because they want everyone inside. Liability can also be an obstacle for them. But if you contact trainers directly, anyone with equipment should be able to put together a small bootcamp.
Best of Luck,
