Without knowing the specifics, I suspect each shop will average 5 minutes (prep time, call time, report time) if all goes well. That assumes that the phone is answered on the first try and you are not put on hold, and that the report is very easy. So, 5 minutes means $12 per hour. That sounds low, but you have no expenses and no downtime between shops.
But - $1 for a phone shop is very low. I'd be inclined to try a few if they allow you to see the report in advance and it looks alright. I am dubious.
Shopping Southeast Pennsylvania, Delaware above the canal, and South Jersey since 2008
