I can find a group of active traders (my ex-coworkers) who are wealthy and don't need to have leverage. Do you think they will join a prop firm if I start a sub-LLC? What benefit will they get from joining a prop? How do I start a sub-LLC? How much is the initial cost, and the operating cost? If you currently run a sub-LLC business, what risk do you have as an owner of the sub-LLC?
