Not knowing much about your location - rural, town? Its difficult to be exact, but you could look at things like Parish magazines - anything that is local and gets delivered door to door. Advertising in these is very cheap and targetted.
Or do a swap with a non-competitive business close to you - a hairdressers for example - you give them 100 leaflets to hand out for you - and in turn you hand out leaflets for them....
Just a few ideas..
