Sole proprietorship business credit

[Rene Calacuayo]

I'm trying to build business credit from scratch, so far I have my DBA filed with my state, my business checking account, my duns number, website, business phone number, business email and virtual business address. And now I'm looking into a few trade lines. The more I'm looking into it it kinda seems like I'm going to need an LLC instead if I want to get credit cards from banks once I get to that point. So far can anyone tell me if I'm on the right track and if not what I can do to get there. Thank you
