tennis court construction and funky shape of tennis net post footing (2025 Update)

I'm making a home tennis court out of an asphalt paved area. I'vealready bought the net and posts. The specified concrete footing foreach tennis net post is a 30" square at the bottom, tapering up over aheight of 42" into an 18" diameter circle at the top. A drawing is at I use 3/4" plywood to make a form strong enough to contain thismuch concrete without blowing out or breaking? I think the bigger jobmay actually be cutting out a big enough square out of the asphalt(32"?) so I can then rent a 30" auger to dig 42" deep, cut the cornersout to a square with a shovel, and then drop the empty form in, andsomehow hold it down while pouring the roughly ton of concrete intoeach one. After stripping the form, backfill with dirt and repair theasphalt. Any suggestions for me? I'm thinking readymix concrete forthe little over 1 cubic yard I need to avoid all that mixing, and it'sprobably cheaper than buying eighty 80" bags of concrete mix.
