Boost social presence across Pinterest/Instagram/Facebook/Tumblr

****PLEASE READ**** I'm looking for some help boosting the social presence of my new business across quite a few social media platforms. I'd like someone to prepare a strategy to increase growth steadily over time. My main focus currently is building my Pinterest, Facebook, and Instagram accounts, but could use some help with Tumblr as well if you know that platform. The ultimate goal of this is to build an audience that I can market to in the future. ***Please provide a strategy and ideas in your proposal! If your proposal sounds good, I will reach out with further information to help your proposal. Thank you!!!
