If you are going to do an interview leave magic at the door, unless that is specifically what the interview will be about.
I have found that magic has helped me in getting better tips at a resturant I work at. Also if you can go by some daycare centers and see if they would mind if you perform for the childrens free of charge. Charity events are also a good starting point.
Later on you could move onto other things, Trade Shows, live entertainment, amusement parks.
I kind of started backward though I did magic in local Boys and Girls Club and then moved to a theme park for one season and now work in a resturant. It all depends on you.
