Should travel advisors sell experiences before flights booked what do you think

I sold a full set of experiences to some clients for a trip before the flights were booked, then the air quotes jumped and the clients left I am left with deposits tied up suppliers asking for payment and a very unhappy couple who think I promised them a complete itinerary when I had not even secured their departure dates.

Tbh I thought I was being helpful by locking in the good stuff early Instead I made a mess that is going to take days to unwind and probably cost us the booking.

Is there something i can do to fix this situation?
