My channel: a YouTube channel about [niche], with [number] subscribers and [number] views per month.

Build me a full income blueprint that covers:
- an estimate of AdSense revenue
- the 10 best affiliate programs for my niche
- ideas for digital products I could sell
- a sponsorship rate card suited to the size of my channel
- the potential for merchandise
- a model for a paid community
- opportunities for a course or coaching

Then add up a realistic monthly total of all these streams for each of these channel sizes: 1K, 5K, 10K and 50K subscribers.
