here at my shop we use used 50 gallon pickle barrels for composting in. they have a threaded lid with a diameter of about 12", and are usually cheaply available locally through craigslist or a google search... anywho, we drill a bunch of 1/2" diameter holes in the sides and bottom, add our green waste (always an abundance around here,) some kelp meal to feed beneficials, and roll the barrel a few times a week... i've gotten the quickest compost using this method, less messy than many of the "compost boxes" on the market.
the other nice thing about the barrel is that when seeds do germinate, its generally fairly early on in the process, and eventually the heat process and the rolling kills them off and adds to the green matter in the mix.
manure is great if you've got some redworms that need feeding, we've used a mix of horse and rabbit manures, combined with green waste, and cardboard or coconut fibre for the initial bedding... worm casting production requires lower temps than compost for the worms sake, but otherwise is pretty much just as easy to do, and temp control can be achieved simply by using a wider than tall box, switching sides that material is added to so the worms can go to the other side and hide if it gets a little warm for them...
