Years ago a guy at Home Depot discouraged me from buying a big plastic compost bin from his store.  He told me to start my compost pile at the edge of my garden and layer brown leaves, grass clippings, table scraps and newspaper.  Then mix in 1 cup of miracle grow in a gallon of water. add 1 cup dishwashing soap and a can of soda (not diet).  Mix it all up and turn every few days.  I add to it with kitchen scraps and in a week or two I have nice warm soil for my organic garden.   Don't put any protien or dairy in the compost or the rodents show up.  I rarely have to add soil bags in the springtime.
