Have you been residing in the U.S. doing independent contractor work and selling support for your open-source projects from the U.S. to other U.S. states, Germany, Australia, G.B., etc.? If so, let me know, and I'll definitely send you something. It would be terrific to have help! I'm more interested at the moment in just basic things like the legalities of dealing with these states, if I really need something to help with the various sales, etc. taxes and what kind of plan to get or whether I can farm that out via some reputable e-commerce solution that handles these things already, how to make contracts and quotes for these companies. How to translate "work for hire" and "you are not paying me for copyright for code I write in this open source project". Whether I need to be incorporated to do business with them. I know LLC is primarily to write off taxes, and that I'm fairly sure that I need business insurance, because I don't want to lose my life savings in a lawsuit. Basically, I need an accountant with lots of U.S./Int'l experience, an international lawfirm, a psychoanalyst, a friend with similar experience, and a few advisors.
