I was actually thinking about entering that market. Talked to two friends of mine (also into carstuck) already. Problem is that you need quite a bit of money upfront. Wanna buy a second car just for the videos as I don’t wanna take my daily for this. Think of all the cleaning. LOL. But put some money on the side already though 
We probably won’t become rich from our videos as I also work full time and already now barely have any spare time to go out for a drive in the mud but we’ll do it mostly for our own pleasure
So any ideas, tipps or advice how to get started are highly appreciated
