Mines done professionally, looks good, but I’m not sure if I can measure how much work I actually get from it, probabaly less than a job a month.
I’d say 80% of my work comes through my website and 20% a mix of recommendations and walk ups.
Toying with the idea of getting a transit custom sport next, might not bother with the sign writing, may just have a small logo on each side of the van.
