Welcome to the wide world of composting!
There are a bunch of different ways to produce compost but I try to produce it with the least amount of investment possible. I like to make compost piles that touch the ground in order to let all of the microbiota of the environment to inoculate my pile. I believe that compost can be produced without monetary investment MOST of the time. The key for my success has been assembling a big enough pile that warmth can be formed at the core. I don't turn my pile as much as I'd like but I still have success. Compost, at a base level, involves highly nitrogenous materials and highly carbon rich materials intermixing and being broken down by microbes. I shoot for a rough mixture (C:N) of 30:1 carbon to nitrogen. If I need to get my core hot, I utilize either used coffee grounds or urine to give a nitrogen boost. This works in place of a purchased compost starter.
What is your
compost setup like? Do you use a pile or maybe a tumbler system?
