I'd quite like to move my wife's maths business away from Calendly. But unfortunately Cal.com doesn't support payments for events yet. So that will be a sticking point for now.
Would something like this fit your wife's use case? And aside from payments, what else are you dissatisfied with on Calendly that makes you want to switch? Thanks!
I'd suggest registering TalkWithMe.com and using your talkw.me domain only as a shortener to redirect people to the main site.
And good call on the second thing ;)
