Surety Bond for Dealers

I have been a mobile home dealer for about 4 years now. I am licensed and bonded in my state. Recently, my bond was up for renewal and was denied because my credit score has since dropped. Does anyone know where I can get a bond to renew my dealers license without paying many thousands of dollars? I can’t get my dealers license renewed until I have my bond. This basically cripples my business if I can’t get a bond. Are there any other ways to get a bond for my company?

I am in Oregon, and they require a $10,000 bond. I bought one through my local Farmers Insurance Agent for $150.00
