If you're going to print some more, stick all your services on one leaflet.
I'm guessing:
Carpet cleaning
Jet washing decking, patios, driveways, paths
Fascia soffits and gutters
Conservatory roofs
Softwashing?
Gutter clearing? (got a gutter vac?)
Do a leaflet especially for existing customers only. Guessing you've got around 300?
Get some 'nice before and after' pictures. As it's for existing customers don't mention window cleaning (they obviously know that). Focus their attention on all the other goodies you offer.
This time of year and for the next few months, it would be like a 'pick and mix' for your custys.
Blimey, you're like a 'one stop shop' for cleaning.
You're bound to get at least 20 to 30 jobs, doing something!
Get on it!
P.S. I used to be a graphic designer for over 20 years, so when I get bored I just design another leaflet.
Right! Traffic has cleared so off I go..."Hi ho hi ho it's off to work we go..."
