Very good question! Considering that I’m also trying to save as much as possible as well (even though I don’t have any comrades and feel lost on that subject), I’d be very unwilling to buy anything other then chemical free essentials like soap (my source is about $2 a bar) or toothpaste. I would think that making something as a group to sell would be two fold, first it strengthens the group to make things together and second you can sell it to make a little bit extra money. And then once you make said product, you need customers and that’s not so easy. Like me for instance, I may never check this post ever again so how would I even know to buy from you? Not so easy times right now for trying to separate from the mainstream it seems.
Also, maybe some kind of gardening or lawn care service may be a good way to bring extra cash and could be a teamwork kind of thing. Lastly, I’d say maybe using the internet video meetings to offer advice, like if you offer that all of you will sit and listen to someone and give them advice, maybe that would be worth it to some people. Good Luck!
