Well, Janice always has her backpack with her and right now it has 5 cans of food(5 TUs), a flashlight with batteries(1 TU), and 5 Chem light sticks(1 TU). So Janice has 7 of the TUs. And she might be able talk him down a little on price, (Diplomacy +7).
With a few more TUs of stuff we could talk our way into what we need.
(Also, Janice might use her 'Far Hand' to procure an item or two. She's done it before, many times, to get food.)
Just saying, so you know what she might be able to help with.
