Do you think that flyer's are a good idea?

No to ping out flyers to strangers. Make a list of the things you can do like walking a dog, painting, cleaning out a garage or basement, yard work, babysitting, dogsitting, etc. Put on the list that you are saving to go to summer camp (or whatever so they know you just aren't bored and are earning extra money). Then only take these to people you and your parents know in the neighborhood, friends, and relatives. No strangers because you could hand one to some guy that just got out of prison and is a pedophile.
