You could always try an informal payment scheme. Find existing storefronts that have MSB licenses that do currency exchange, ask them to take payments for you. End of the day they deposit to your business account. Now you can have cash accepting storefronts. Find an easy yet secure method for these stores to notify you of cash payment and release the coins.

This is better than cash deposit directly to your bank account because of MITM fraud attacks, and because banks hate people coming in to deposit cash and quickly try to shut down the account. Again I'm not a lawyer so I don't know if you'd need a license for this in the USA but overseas it would work in countries that need this service, like Pakistan/Philippines/India.

EDIT: I would imagine, if you do quite well, you could sign a 1:1 agreement with companies like Bitpay who are looking for USD, and have BTC, and you have USD and are looking for BTC. win/win
