mine cost £50 4 sides, but it was a mate who did it. make sure you get the wording right the 1st time.
i have residential and commercial in large letters on its own and
we also clean, gutters, fascias, drainpipes, upvc, conservatories and driveways
plus a freephone number and mobile.
a fancy pic would be nice but not essential.
ps only 2 people in 2 1/2 years have become customers from looking at the wording on my van.
but at least it looks professional,.
