Currently I won’t do that at all because (1) way too dangerous, (2) way too expensive, (3) not obvious how to start.
Honestly, I’d love a subscription model for this. I’d pay an initial fee for training. Certify me when I’m safe. Then let me pay to get the airplane and fuel for a specific journey. Handle all the maintenance for me. Check my work on planning. Have a real expert available on integrated speed dial to talk me through anything complicated.
If this winds up being fun and fast, I’m willing to pay more for it. The specific trip I’m looking at would cost $800 to fly with a standard airline. I’d pay double that to self-fly. The premium gets me convenience (I control the exact departure time, less airport hassle) and adventure (flying!).
