Here's the BIG problem
In order to stay fully booked you have to continually market and promote yourself, if you don't you won't get booked.
Also, associations ONLY give you "exposure" in a sea 🌊 of your competitors by letting you:
Purchase a table/booth that your buyers don't even want to visit.
Do a workshop where 5-30 people will show up.
Beg them for the contact list of the people that attended.
- Pay for "sponsorships" that don't move the needle.
And exposure can get you booked...slowly. The question is how much time do you want to waste?
