I prefer van signs to sign writing. I could have had my van wrapped for £300 by my grandad who is a retired sign writer. He still owns a workshop but leases it out to his old apprentice. He done my last van for £100!
I decided against it when I bought my current van.
I prefer the idea that I can advertise in only the area's I want to advertise in, or chuck the signs on when I'm doing commercial.
I have a few areas that are a bit far and I don't want anymore work, so I just remove the signs and go in quietly and stealthily, get the jobs done and get the hell out of there!
