How do I speed up composting?

Hi there I have a big pile of leaves and sawdust in a planter I want to use this summer. It's not braking down quickly enough as it stands right now to be able to plant in it. Do I need to add alot of greens to help it break down I can't find it easily. Would coffee grounds help? I can try to drive around asking coffee shops for some. What about if I add urea/pee? Would worms help? How long would it take under ideal condition to compost the leaves and sawdust if I add enough greens? Thanks for your help!
