Help me finish the Course on Band Orchestration!

I really want to be able to finish the Course on Band Orchestration.  It’s a much bigger project than I’ve shown on the website so far.  If you’re interested in helping, please consider donating to my GoFundMe page.  The final result will be a book you can hold in your hands!  I take that back, the final result will be three books you can hold in your hands.
