Good Luck! I am a grower of native and edible plants for many years. I have been a plant vendor at many shows and markets. Customers have less money to spend and the costs of doing business is horrendous. Plus travel expenses! 15% off the top is way too much. You are taking all the profit. No wonder you can't find vendors. And plant sales are outside!
If you had a sale with a proven sales record, I would give you $50.00 for a 15'x15' space outside.

Well- this is a plant sale put on by amateur growers and is not geared toward professional growers/vendors. It's where the average community gardener can go with their seedlings and divisions and make some extra cash while socializing with fellow community growers. Quite frankly, we would not be looking for someone with this type if attitude anyway. We are looking for a more community-oriented individuals with a sharing spirit. Thank you for your response anyway.

And my apologies! I should have specified this in my original post that we are looking for friendly, amateur, community-based individuals looking to make some extra cash to support their beloved hobby and to commune with other gardeners. My bad!
