6. Alternatively. Pay me loads of money to come down south, put me up in a 5* hotel and I'll happily sit beside you for 40 hours.
I will settle for a 4* hotel and loads of money.
But honestly, just hang around the airport for a few hours and talk to people about your problem. My guess is that within a few hours you'll have several offers of pilots that will fly with you for free. I've had those offers (and made good use of them) on several occasions, and I have made the same offer to others too (and they made use of them too).
You might also want to look around the airport for any flying club, as opposed to a flying school. Clubs generally have a more informal atmosphere, with more pilots who fly just for the fun of it, and will seize an opportunity to fly RHS for free, with both hands.
2. hire an instructor at Stapleford to sit in the RHS. I think you can log the time as P1S ?
If you are fully licensed, current and everything, then you are 100% entitled to log that time as P1/PIC. Just because you happen to have an instructor sitting next to you, instead of an aviation-novice passenger, doesn't change your status as Pilot In Command.
But... Beware that some hour building instructors insist that you log P1/S or PuT (aka "dual") while they log PIC. They need the hours and think it's OK that you pay for them. That's not in your best interest in this case, particularly since you are hour building too.
