A great tip to help promote yourself in public is by visiting colleges. You should carry about a hundred flyers, a stapler, a pen and some tape. You should try to get permission first to see where you are allowed to post so your flyer wont be torn down. Some of the best places to post your flyers would be in the class halls or the main location where young students hang out. Most college kids are always looking for ways to make some extra money so approaching some maybe in your best interest.
