Adagold are essentially a brokerage/ middleman. In a previous life I did quite a bit of work for them but operating for another operator.
Something like I work for XYZ Aviation and Adagold have the job, they speak to ABC, DEF & XYZ, who ever had the best deal won.
Lots of governmental work went their way when the government concerned did not have internal lift capability or needed discretion.
Very above board, they have been around a very long time and are
NOT the kind of AN-12 in the middle of the night full of "used machinery" kind of operator............
Well not when I knew them
