However, if I could counter that, with a promise (however vague) of a new potential client-base, as there might be lots of good bitcoin people, that would love to help make a positive change in the world, at no extra cost.
You can just use some more payment processors - more exactly find one that also accepts Bitcoin.
Like any business that pays his taxes, your business needs your local currency, clearly. Getting Bitcoin directly would add more unnecessary paperwork, I guess.
If you get a payment processor that accepts Bitcoin among other currencies and payment methods, your business CAN get some more customers because of the "new payment method", although for the company itself everything will go in the same way as it did until now. You'll have much less to explain.
