@Adolphus Fletcher - If you're main goal is to build business credit there are different avenues to do so including: obtaining and unsecured line of credit for the business, applying for a business credit card, applying for business accounts such as Home Depot/Lowes, etc...

I'd attack the credit report :) 1) lower (pay down) whatever accounts have a high utilization percentage 2) contact each of 3 major consumer credit agencies and get a free report, then dispute every hard inquiry that is *NOT* associated with an open account 3) call the credit cards you already have established and ask for a credit line increase -- often can be done online and they do not verify income, hint hint. 

Do, you have any other higher interest debts for example a credit card?

They use credit cards for emergencies (Yeah, right..) 

It's not like a credit card that can keep climbing. 

Also, I am in the process of creating a business logo so I can make some all important business cards and swag (who doesn't want that!)

Pass out business cards to strangers and call friends.  

I also suggest Michael Gerber's "The E-Myth Revisited" as well as his "E-Myth Real Estate Investor" collaboration with Than Merrill and Paul Esajian.Remember - 90% of this business is marketing so don't let all the other stuff, like obsessing over business cards, get in the way of that.Good luck!

I believe many in your shoes also struggle to differentiate between mortgage debt and unsecured debt such as  credit cards.

They are trying to protect you from yourself and your efforts to over leverage yourself. because that's how you'd get to your next post of when the house of cards starts falling down and crushing you under it all.
