Hi Neil,
All leaflets actually work. depends on a number of different factors, if anyone could say to us, put this, that and the other in your leaflet and you will get exactly X% return we would all have the same one. One major factor that you will hear, see and experience it comes down a lot to the NUMBER of leaflets that you put out, keep putting them out and your leaflets WILL work .
You may not like some of the ones that Mike has posted for different reasons, it may not be the way you wish to protray yourself or your company, pick the thing from them that you like and it will help you put together your own.
I have been using a version of one of Mikes for the past year and it has kept me going but also because i kept delivering them. IF YOU DELIVER THEM, THEY WILL CALL. (ha ha).
Keep with it you will get a design that you like and gives the information that you want.
I hope this helps.
Regards
John
