Help with base !!

I've spent the past 2 or so days trying and failing to put leaves on my base and eventually I just gave up. I would like to hire 1 or more people who are better builders than I am to place the leaves on my cherry tree base. Will give 30 diamonds as payment (if more than 1 person, it will be 30 diamonds each). My nether roof coords are at -423 502. There will be a sign pointing where the materials are. Thank you!! :)
