There's a place in Dallas called Sky Helicopters. You might ask them what's feasible. I don't really know that much about them, but they've been around for a while and I talked to the lady once and she seemed ok.
If you live in Southern MO, it might not be too far away and there's a motel directly across the road. You might could do it in two weeks - especially if it's an add on.
No, you're not making too much of it. It's a business and you're a customer. You deserve better for your money.
