I own a small business, and looking for a small loan that would be secured by the equipment bought..?

I currently own and operate an inflatable bounce house rental business in Las Vegas, and I am currently getting more customers than I have equipment, so I am looking for a small loan to purchase additional equipment, which would be the collateral for the loan..However, I do not have good credit, but I have reestablished my credit with a couple of auto loans, but my credit score is still to low for a personal loan, or so I have been told by other lenders..The payment for this loan would be no problem, because the income generated by this additional equipment, would be far above the amount owed every month..This equipment I am looking to purchase, is new equipment, and would be very good collateral..Thanks
