Craigslist always has roommate stuff. I considered renting a room out and decided against it, but saw a lot there when I did. People list where they want to live, if they need to be on bus lines, what they need (like wi-FI), what they can't deal with (like drugs or guns), pets, smoking preferences, etc.
Being as I'd want a Roommate Agreement much like Sheldon & Leonard's and most of the people looking for rooms wanted to smoke pot (there is a number for this, like 423 or something - "423 friendly" or "Need 423-friendly"), I gave up before I started and just asked my neighbors to call me if the house caught fire or something while I was out of town.
I'd absolutely meet people before plunking any money down, if I were you!
Good luck with the move and welcome to Central Florida!!
