Social media research

I have a long (but segmented) piece of creative historical writing I wish to send out, free, online, to whoever might be interested in reading it (readers of poetry, people interested in 17th C history, students looking for stimulus material). It is poetry and historical notes based on events leading up to and the early stages of The Thirty Years War. I want to hire someone web and social media savvy to find groups who might be interested in downloading the piece. As the 400th anniversary of the outbreak of the war will be May 2018, there will be increasing international attention on these events over the next 18 months. (Note: Material is under copyright.)
