I'm not getting the ad in that environment Richard.
Given the type of people coming through, what primary service would you be expecting them to buy?
If moUld remediation during their renovations, then I see it working, but if it's carpet and furniture cleaning, then the ad doesn't gel for me. I'd recommend a variation of your church ad.
I had a stand in a design facility for a while, I can't find any photos of the actual stand, but here's the photo I did up as the huge backdrop behind it. I was targeting rugs, leather, carpet and upholstery and got that all in with my van in the background.
This ad looks a bit busy, maybe the truck and staff image could be scaled back a touch smaller. Also, thinking of designers, think meticulous, I'd sharpen the image up somewhat, like the white in the spokes of the dehu, bring the blue through.
