Build social media following

We are a new literary press, www.jnewbooks.com, and are looking for a social media manager. We would like help creating and growing our social media presence.

I am not sure if this is something you do but we would also like help assembling a group of influencers , podcasters, ect to help get the word out about our books. We give them a code and every time someone purchases our books with that code they get paid.
Thanks for your time,
