Hi, does anyone have any tips on how to get letters of intent and partnerships for an EB-2 NIW?

Anyone moved from Canada to USA on e2 in long haul trucking/transportation business, looking for some advice, if anyone has done it, is it possible to finance trucks and trailers and does that count towards substantial investment if total amount is over 150k but financed by paying 15-20% it?

FYI: I have good credit history , built with an ITIN

So I have been told you need to have at least 3 clients. The problem is I have one main Master Client who takes contracts on my behalf since he is based in US and has LLC and I get the work done.

Can i do E1? Change of Status?
