Looking to trade shortboard for longboard

[Circle K]

Hey everyone. I'm new to this forum, this is my first post. I'm living in Clearwater/St. Petersburg Beach, FL for the summer but normally I live in Gainesville, FL. I have a used shortboard that I got for Christmas when I was young but never got any use out of it (there aren't any waves in St. Pete). Now I take frequent trips to St. Augustine Beach and Daytona Beach during the school year. The problem is that I would rather have a longboard but don't have the money to buy one seeing that I'm only a college student. Does anyone know of a place where I could trade my board? Do surf shops offer a thing like that? My board is in fair condition and is 68"x20"x2.5". Thanks everyone!!
