Which iPhone app is best for scanning and faxing mortgage papers on short notice?

Hey folks, I am in the final stages of closing on a home, and my mortgage lender just requested several signed disclosures and bank statements sent over via fax right away. I have the paper copies in front of me, but no scanner or home office equipment. I need an iPhone app that can take clear camera scans of physical pages, clean up the contrast so the numbers remain crisp, and fax them over immediately. Any recommendations?
