Comprehensive Sales Pipeline Dashboard

I'm in need of a dashboard specially designed to display sales data in a comprehensive and visually appealing manner. Should prominently feature important KPIs: revenue, number of sales, average sale amount, and win rate. The data, presented on a monthly basis, should include trendlines or comparative metrics that allow for a dynamic view of progress over time. Freelancers should have prior experience in dashboard design, data visualization, and a firm understanding of sales analytics.
