Of course you should!
Internet nowadays are easy to get and I think it is even better chance to promote ECA to those without using internet, explaining them all advantages if they start to use it, and especially as your ECA!
With right aproach and strategy you could easily get interest of those businessman for spreading their business online too. You have to admit that there are plenty of advantages of online business, so go ahead!
I wish you great success!
