Trying to verify page for my business

Hi. I just created a facebook personal page and then created a separate page for my business following the instructions. It is up and running, but when I try to get the page verified I am running into a problem. First it wanted me to enter the phone number and verification code, but when I did that it did not accept it. Now they want me to submit company registration documents. Problem is I am doing business on the Web under a dba that is not the same as my registered company name. So I don't know what I can submit that will satisfy the criteria. I have been doing business via PayPal and the Web for over 10 years, but always using the dba. I would be grateful if anyone has any suggestions.
