On your point about not wanting to conduct an ICO because you don't need millions of dollars. You can do a smaller ICO with not such a large raise. Go back a few years and ICOs never raised millions of dollars like they do today. Alternatively you could seek investment through another source, that might enable you to hire a lawyer who can help expedite the process.
