Most hardware or farm supply stores carry “welded wire mesh”. It is like chicken wire but more substantial. The openings are 1 inch by 2 inches and comes in about 3 foot widths. An 11 foot length of this will a cylindrical bin of sorts. It will come off the roll and want to curve, which is helpful. Three twist ties will make it into a compost bin, 3’ high and 3’ diameter. Or you can use cattle fencing, which has larger holes; or hardware cloth, which has smaller holes.
You can get by with one bin but two are best.
Cost of the wire mesh varies, big box stores have it for between $50 – $60 for a 3’x50’ roll, which is more than enough.
Throw your grass clippings, leaves, tea bags, coffee grounds, non-meat kitchen scraps. Shredded newspapers, ash from a fireplace. Occasionally you can throw in a shovelful of soil. (Top soil, plain garden soil, soil from your garden). Water the contents!
When the first bin has “percolated” and is full, undo the twist ties, and using a pitch fork pitch the contents into the second, empty bin. Add a few handfuls of soil, stir, moisten and let “cook”. You can add a black plastic covering to help keep the pile damp.
