New to surfing but not waves

Hey guys, let's get this out of the way....I AM A SPONGER! I always will be. If you hate spongers im sorry, i dont snake and i dont drop if you got priority. Your surfboard hurts a lot more then my foam.
Anyway, I kinda want to start to surf mixed in with bodyboarding. Im pretty sure i want a fish thats similar to a shortboard, because my waves are pretty small a lot of the time (East Coast US) and since bb is my primary sport I dont want to spend a whole whole lot of money, but i want a pretty quality board too. Just something to have fun on, that i could carve well with. Im new to surfing, but im not new to wave mechanics so can anybody give me any help?
Im ready for you guys to start bashing me cause i sponge now
btw 5'7 155 or so so i was thinking somewhere around 6'0 6'2 in length?
