Social Media Marketing/Fundraising/Admin/Personal Assistant all rounder needed

A fun new project, we are launching a new tech project with social media and crowdfunding, so I need to find someone capable of a number of varied skills. Some social media marketing experience, to build a Twitter following as well and managing the Facebook presence, and to promote the website and Social media accounts to relevant forums, pages, and other influencers. Also, we need to build, maintain, and run email campaigns as well as general office skills such as admin, organizing, and research over the internet.
