The great thing about business cards, is that you don't have to currently operate a business to sign up for them. Go ahead and brainstorm one, even if the income is $0, and you can sign up for any of these cards. You aren't required to have a business ID #, but some applications give you the option to provide one. If you'd like to sign up for one click HERE. They are free, and it only takes a couple minutes to complete.

I have rated them based on the criteria I feel is most important, including transfer fees, estimated credit limits, card perks, etc.

Many times the credit limit given out with business cards is higher than for personal cards. This makes them a vital part of your strategy if you're looking to see that line of credit skyrocket. This category is pretty slim right now, but the cards that are here offer very good profit opportunities. All of these cards offer free balance transfers.
