Feels like Starting Never Ends

I built, what I know to be, a really good product because the few clients I have absolutely love it. They don't just tell me; they use it like an addict on drugs.

It's hard to convince others they'll love it before they use it though. There're so many apps. I'm trying to make a free demo so users can get started, but I'm afraid users and bots will use up tokens. Gotta rip the band-aid off I guess. Any tips?
