Hi ​@Christopher's04655 - Thanks for reaching out!

Two ways we can go about this:

1. You can create a One-on-one event with a duration of 5 minutes, and set the Start Time Increments to 5 minutes as well (This is the lowest number it can be set to). This would allow a booking to be made every 5 minutes for those sessions.
2. Alternatively, you can use a Group Event Type and set the invitee limit to 50 with a duration of 90 minutes. This way they can book in to the timeframe correctly. 

In regards to the payments, we have two integrations available for users to utilize. This would make it so invitees would need to pay before the booking is complete. I’ve attached help center articles below:

Calendly + PayPal
Calendly + Stripe

Let me know if you have any questions on this!

Thank you David, Option 1 is best. Where do I set the start time increments? I only see 15 minute options

Of course!

You can adjust the Start time increments by editing your event, selecting more options, then under booking page options it can be adjusted there:
 

Let me know if you have any other questions!

Thank you~!
