There are many job opportunities available for the modern day close-up magician. Pizza delivery man, ditch digger guy, Wal-Mart greeter... etc.
Seriously though, there are many venues that you can find to practice your craft. Consider restaurants who host a kids night.
Companies nationwide are always having appreciation banquets for their employees. Strolling magic in this type of atmosphere would be welcomed before and during the dinner or cocktail hour.
And then there are trade shows, but these types of engagements are usually gobbled up by full time pros with many years of experience under their belts. But hey, it's certainly a goal for you to work towards!
Best of luck to you!
