Here is the official proposition - which was discussed briefly over private communications - Corentin Brothers Limited is offering you, the Jumping Zoners:
As we are in need of Ship Hull Panels, we would like to propose a mutually beneficial trade: 30,000 Helium for 35,000 Ship Hull Panels. The Helium will be ready for you to pick up as you arrive with the Ship Hull Panels.
If this deal is acceptable to you, please reply with a possible location and time for us to meet. In order for us to quickly transfer the Helium, the most preferable location would be near the CBL base in Pennsylvania.
