The project seems really well put together but until you figure out your ideal target customer (and their needs) I would hold off on pricing it too high. Maybe offer it for free, get some learnings and as you add more value and get more clarity on your target group, you can then ramp up the price?
Yeah I've been considering that. Probably more likely that I'll lower the price, learn some things, then ramp it up. Free feels hard to reverse and the difference between "I wouldn't pay at all" vs "I'd pay less than that, but something" is pretty big (and important to me unless I figure out another way for the project to get paid for).
