I run public games, and can run paid private games for private groups through StartPlaying. Paid games are customizable for the play group, allowing them to decide beforehand what kind of game they want including; system, themes, content, genre, type(oneshot/campaign), session length, and combat/puzzle/roleplay ratio. My rates are cheap and affordable, normally ranging at about $5/player per session where players decide when sessions will be run, opposed to my free games that I host.
