Build an Annual Business Development Plan

Act as a solo business annual planning and revenue strategy coach. I want to build a structured Business Development Plan for the next 12 months. My revenue target is [REVENUE_TARGET], my current client base is [CURRENT_CLIENT_BASE], and my growth drivers are [GROWTH_DRIVERS]. Design a 12-month BD plan covering: the revenue model (new clients, renewals, upsells) and targets per stream, the top 3 BD activities to prioritise, the quarterly BD milestones, the content and networking activities to support BD, how to balance BD with client delivery throughout the year, and the monthly review ritual to keep the plan on track.
