Applying for a small business loan from bank, what should I bring to be prepared? Some sort of bus. proposal? - business loan proposal

We (my husband and I) go to the bank tomorrow to ask for a small business loan for a mortgage to. We already include 1 month ago.

My husband is a mortgage loan officer and is 5 years. Experience. We will use the money to an office, advertising, rent, supplies, etc.
Our only concern is that our credit is bad.

What should I bring to convince the bank about it, that our business would be a good investment for them?
