I have a RISO

I certainly could show you one Mike. Although we know what will happen. It will get picked to fck for the way it looks and some smart arse will tell me they won't work.
Here's a formula for anyone interested though if you are in Pompey please get the glossiest thickest paper you can find and pay a leaflet delievery company to do a 50k drop.

Go online and seach 100 greatest sales copy headlines, or something like that. Pick 3 that you can adapt for CC.
Make the headline big and bold and your number on the bottom saying CALL NOW or CALL BEFORE (date)
Put your copy in the middle ideally with a good offer
Put your testimonials on the back (which are local and have REAL NAMES AND ADDES)
Take the headlines and put each on an a6 column of a4 sheet (that's three ads per sheet of A4

)
Get your paper from the cheapest possible source. That could be Tesco, Aldi or where the fast track boys get their pink from
Find people to deliver for you and ditch them as they let you down, keep the good ones happy. Keep doing this.
Everytime you take a call ask them the headline. Keep the most popular for your next run and add two new ones. Keep doing this.
Most printers want to do colour glossy rather than mono. That in my experience just means more profit for them not you.
Crappy looking leaflets also work in nice areas, but the headline and copy will not be the same for a cheap area. This is where people go wrong.
You can also really localise ads when you have your own printing ability and this can really make a big difference to response.
Do at least 30k before coming back and moaning at me.
Hope this helps.
