I’d have to see what you’re offering and what your social media game is like.
If it was me, I’d probably do the garage little by little and make it a gallery / home office / place to store your equipment as just a cool/nice part of your home - and then the social media is where the focus needs to be to make sales.
Are you in a city like Denver etc? Usually there’s a pretty active online community among the wildlife photographers. Probably gotta find the people doing well and see what they are doing…
I’d say the garage could be cool as a home office / nice place for your hobby but as far as making sales you’re going to have to put the work in online.
