Another idea you could actually hire a local mail man to tape flyers on the outside of each mailbox in his route... A local mailman I know has 600 homes he delivers mail to everyday, I am sure he would like the extra income for handing out flyers... You could pay him like 0.10 cents or 0.20 cents for each flyer he distributes, alot cheaper than regular mail, or you could do the same scenerio of hiring local school kids to do the same, but to tell the truth I would trust the mailman before I would any kids.
