Monetising FaceBook audience

I run a vibrant Facebook group of 12,000+ members and am building a website to migrate and monetise the audience. I need a specialist to professionally manage and grow the group, curtail external advertising, develop and implement monetisation strategies, and set up/optimise a Facebook Shop if suitable. Deliverables include traffic-driving tactics to convert members into website customers and promote my authored book. Please provide proven experience in group monetisation, relevant case studies, and a clear strategic plan tailored to this audience.
