I have a website and a Facebook account.
I get calls from business owners just like you all the time. The best answer I can give you is this: Find someone who understands the online world and can help guide you through the entire process from: validating your business online, planning, strategy, execution. DO NOT try to learn everything yourself. Continue building your off-line business and after understanding if there's a way to make it work online, find a person to help you do that or you'll end up diluting your time and efforts, which may affect your existing business.
