It may be worth calling around commercial operators in your area and seeing if you can get the name of someone closer who can help you out....
This.
I have found TC very agreeable to a special arrangement when it made good sense, and was born of necessity (geographical common sense). When I needed a ride for my multi engine endorsement, I had a lot of trouble finding an "examiner" who had any experience in Cessna 310's (in which I had trained privately - I had the plane). None of the schools flew them, so their instructors knew nothing of them. I found a qualified and experienced "examiner", but he was not a public "examiner", and rather distant. I proposed to TC and the insurer, no problem, I could fly the airplane solo there for my ride. It went very well. TC inspectors have means to allow some exemptions/exceptions for special needs - if you approach them with a reasoned plan - and a favourable attitude.
And, should you find a more local commercial operator who is willing to help you out in this regard, and you impress them with your easy going, professional attitude, and then during the flight with one of their pilots - you may have just made a friend first hand - that never hurts.
