to do when ur not surfing?- HELP

first of all i live in florida and I've been trying to get into surfing for a long time but excuses have came up here there and everywhere and the waves are really inconsistent here and choppy most of the time,
so I'm looking into paddleboarding on those crappy days since it doesn't require specific conditions like surfing does and i love being in the water and having fun out there
however,, I'm just a kid and i can't afford 600 $ boards
does anyone know if i can get one for like 100 $ ????
lol
or should i just take my 6'2" retro-fish surfboard and paddle around the river my house is on??
**i just want something that is on the water, fun, active/ exercise, doesnt require the kind of conditions surfing does, and won't cost a lot of money! and do-able on a river
please help me out ASAP,
