Lovely tree! What a great way to show your trees.
If memory serves me right you're a member of a very active club? Why not ask if club members want to be part of 'Project Mugo' - there's bound to be a 'techie' that knows how to tweak youtube, a cameraman who you can brief and use to document techniques, a voiceover guy if you're not happy narrating and a special effects person to sort out titling and music. Another source of expertise is, of course, here ... it's clear many people have benefited from your advice and would donate their time if they have it.
