Searching for wholesale produce

Hi all! I'm going to try to sell pies (cottage foods) for Thanksgiving and need big batches of fruit/veg. When I lived in Florida, I went to one of those giant warehouses with lots of wholesalers where you could buy stuff by the flat or pound. (Have You ever seen a pound of basil leaves!?!??!) It was open 3 am til 10 am and anyone could walking in and drop cash on whatever you needed.

I know this must exist here in Houston but I don't know how to find it. Does anyone know?
