I don’t fly the AS350/H125, but I’ve been tied in to a Part 61 training and Part 91 commercial op for the past year and a half. Operating aircraft for compensation/hire is not for the faint of heart, but it can be extremely rewarding in several ways. There’s way more that goes in to legally moving people and products than most think.
Scott Urschel at Pylon Aviation has been in the business of buying and selling aircraft for many years, and I believe he consults as well. He might be a good guy to get ahold of, at least as a starting point. He could likely walk you through quite a bit and get you pointed towards other contacts including investors and insurers who could help you decide if it’s something you want to get involved in.
Performance wise, the H125 is a phenomenal airframe. I have several former instructors and classmates who fly them and they all agree.
