Alternatively, I would just use a geobin. I used to make rabbit cages out of those wire shelving units and while they'd work you'd have to connect the grids together with zip ties, ideally UV resistant ones, and toss the connectors they come with. Otherwise the connectors would pop off every time you move the bin to turn your pile. That seems like a waste. At some point you'd chip the vinyl coating in places and expose the metal underneath which would then rust, too. I can't think of any benefit over the geobin that would make dealing with those drawbacks worth it.
I've never done a traditional hot compost pile or ever used a tumbler, so take this with a grain of salt. I've read a lot of tumbler reviews and watched a bunch of videos and you really need to manage the ratio of browns and greens with the moisture very carefully to make compost that quickly. If you decide to get a tumbler, this is supposedly the Cadillac of tumblers:

If you want to go with a pile, this is supposed to be useful:

John Kohler has a lot to say about this topic, so if you've never seen his review on tumblers, it's worth a watch, albeit long:
This is a video on the geobin:
If you're planning on composting every single thing, this won't work, but I have a worm factory and it's been great for the time I've had it (like 6ish years). It's small and if you shred paper or single ply cardboard, it works well for bedding, which is more stuff not being thrown away. You can also add additional trays so you have more capacity. After the initial setup and wait for the first 6 months, if you regularly add food into it, you can harvest the compost every month (quicker if you're good about managing ratios and have a good worm population).

Unfortunately all my worms died recently due to my neglect, so I have to get more 😕
