I got into this because I can work from home with 3 small children. You can feed worms anything that once alive. You could ask your neighbours to leave a bucket of scraps out the front to pick up on a given day. Tree loppers always have to figure out where to take large amounts of wood chip, ask them to drop it off at yours if you can accommodate it. It's all about context. My context in Brisbane Australia (sub-topics and suburban) will be different to Phoenix or Ontario... all it takes is some phoning around and planning. BTW, carbon sources like wood chip are easier to manage than kitchen scraps. It takes some forethought to manage scraps because it can become smelly, fast. I have been using effective microbes (EM) to pickle scraps in poly barrels for later use with incredible success. I like your 50/50 mix idea, very intriguing. On that, anyone like yourself who has a curious mind, an optimisation mindset and a desire for continuous improvement will love the micro-composting space... so much scope for experimentation!
