Well, there's paid performances, and that depends on how many gigs come my way. Usually when I do a gig it'll be for about 2 hours tablehopping/walkaround for about 200 people. Christmas and Summer seasons I might do this 2 or 3 times a week - outside of these times, maybe once or twice a month.
Sometimes I'll perform for my students if we have a few minutes to kill and someone asks for a trick. That's usually once a week or so. Other than that, I have a bunch of people who really enjoy magic who I consider "test spectators" - if I'm thinking of working something into my professional act, I'll show it to these guys first to see how it plays. Right now I'm working on two items in particular that are going to "do the rounds" in the next couple of weeks.
