How can I get a loan for a 16 year old business with assets, but not cash?

I have been running a small business for the past 16 years. I have a record label that reissues classic rock albums on CD. My website is www.renaissancerecordsus.com . I have been trying to get an expansion loan but I cannot find any banks who will do it without me putting up a house, a piece of land or some other tangible asset. I am also looking for a partner to provide some operating capital. Any ideas are appreciated.
