marketing

So its been almost 3 months since we decided to start up our Answering Service... We have found the most challenging part is marketing.(I think thats a given with all new companies).. I have read all the articles about how to market a new company and they pretty much all say the same thing "social media" .. Which I'm starting to do. I'm still not quite sure how to market us.. Guess, I'm figuring it out as I go along..
