Why not just sell your homebrew illegally? Trust me, it's cheaper and safer. Of course, don't do it in the US where there are laws.
Not a good idea!! But depending on your state's laws you could do a brew-on-premise (BOP) operation. In California they actually call it remote location homebrewing. You would charge for all the ingredients, equipment use, and your time. The caveat is that the customer has to "help". That certainly seems up to interpretation....is it pitching the yeast, bottling, adding hops?? Often thought about this myself....If a friend wants to buy some of my beer for his party obviously I can't sell it to him. However, at least in CA, it seems that as long as he "helps" I can charge him for my time, supplies, etc..... This can be done without a license.....AFAIK there is no BOP license required by either TTB or CA ABC. I don't know how IL is but maybe something you can look into?
