An old joke about new product development at Apple went “First design the icon, then make the t-shirts.”

Setting up an LLC and the other superficial trappings of a real business amounts to making the t-shirts. You have no customers, no idea how to get customers, no insight into the market from a contracting perspective.

You can find plenty of freelancing & contracting advice online, useful and not so useful, if you do the work. Mostly it distills down to contacts and reputation. Posting the equivalent of “I’ve set the table, how do I cook the meal?” seems like a big ask.
