I understand your frustration. I work with clients everyday that are in the same situation that you are into. The key to what you want to do is to build your Business Credit so that you no longer have to rely on your personal credit.

The money you want to get is for your business so why not let the business have it's own credit. This can take awhile to build but you will be much better off in the long run.

Do a google search on "Strong Business Credit" and you will find several ways on how you can be able to get the business financing that you are looking for.

Good Luck!
