I've always used recycled/repurposed materials when making compost bins. Pallets are my favorite, and they can be painted/stained on the outside if you want/need them to look professional. The spaces between the slats allows for aeration of the pile, and I will, either, staple wire along the interior or use cardboard to line the interior, which acts like a "net" to keep the contents from spilling out. You can line the pallets side by side to create the desired length; and I will also use the smaller pallets as dividers to create sections for the piles I turn.
I've also used recycled poultry/rabbit wire that was just staked in place like a cage for the pile. That isn't as sturdy or pretty, but it's easy to move around if you need to compost in a temporary area.
Sometimes I just make piles on the ground without a "bin" around them. Personally, I like to have the "order" and edges the bin creates, but the process still works the same. This could be an issue, however, if you have varmints or domestic animals that may want to dig for food in the piles.
Congrats & best wishes on your project! It sounds like an exciting venture!
