I am looking for an appointment booking calendar. this

Hi. I am looking for an appointment booking calendar. this seems to be near what i need but each user woukd need to sync their own google calendar to their own profile. and hence receive notifications and payments directly. is this possible? thanks.Im getting a really frustrating message telling me to add more details.....well...i havent got any more so i am just noe writi g nonsense....what a silly thing i have to do as a paying member. these details should be in a box prefill requirement or something. who put this silly feature into a support request?????
