Hi there, I think I may be able to help. I've been designing infographics for organizations, publishers, and for my own company's content marketing for about three years. I just launched a site aimed at offering affordable infographic design that might interest you: http://www.thepowerofinfographics.com/ The site shares some infographic ideas, includes a small portfolio, and has some information about my book, The Power of Infographics. If you're interested in chatting about your infographic objectives or have any questions at all, please feel free to contact me at your convenience.

Your touch points will depend on your target customer. A good starting point would be to analyze your different audiences and developing a buyer profile for each. One of the components of each profile would be the channels they use to gather information (the digital places they hang out). From there, you will need to develop a content plan for each channel, then create and publishing relevant content that meets the information needs of each audience. Possible touch points would be email (permission based), social media, direct mail, online/offline ads, etc.
