From a money making perspective, I am afraid you may be behind the curve on this idea. Lots of youtube channels and facebook groups already out there.
If it were me and I decided to move forward, I would focus on a niche that would translate to clicks from your current user base. Maybe shop and garage building and improvements, along with some tool review content. I think you would have a large participation among for ( ) body type clients with this setup.
Just my two cents as a fellow small business owner.
