I would think that most professional services would not run any lumber through their jointers and planers that they didn't sell to a customer. Reason being is that they won't gamble that a stray nail or screw could be hidden under the surface. This is the same reason that some sawmill folks wont run trees through their mill that were in front of or in back of their houses.
Anyway, I wish you luck. Some of the new smaller bench top planers might fit your needs, but that takes money. ORRRRRRRRRRR, maybe someone on here might live nearby and help you out.
