So I used the company he suggested in his videos: Prime Corporate Services; I paid them and they set me up with 2 separate LLC’s; one in WY for anonymity and one in PA where I reside, but besides that I know nothing of what I’m dealing with and from what I’ve seen on these threads is that I screwed myself and just made my life more difficult.
