J1 offered me OE

I told J1 that I will starting J2 in two weeks, but that I still would like to help them support their systems and tools that i developed for them. They know they cannot match what J2 is offering and that that one will be my primary job. However, today, they offered for me to work as a contractor for them with a set amount of support hours while I work at J2. All things considered, this was basically my dream scenario anyway, but this way everyone is on board.
