A C-Corp, and S-Corp are very similar in there articles and protection and liabilities just as a LLC. The main difference is how they are tax, and how many managing members they are able to have. Depending on what entity you choose they have different tax structures. My attorney said the bank would require the same personal guarantee with any entity. The only thing I can think of is setting up an escrow account with a bank for collateral, or a CD, which was advice from another member. After you have a very study pay history than you can transfer everything to a corporate card or lines of credit.
