Awesome work guys. It would be worth checking out blockpay app which is about to launch an ICO which enables businessss to except all cryptos including STEEM and SD at point of sale. I'm in no way affiliated but like a good idea when I see one and I so happened to have found two in one day :)

Here's an article on it...

Would take a nice beanie with a bobble if you have any plan for future additions to your line.

Best of luck,
