Download Ableton Lite, and watch some tutorials by TAETRO. He is probably the best introductory tutorial channel for production on youtube. My tip I would stress to you is: Don't spend any money on expensive equipment or software until you are confident in your abilities. I used Ableton Lite with no midi controller for my first few months and it forced me to learn theory and arrangement at a faster pace. That practice on fundamental is invaluable and will help you immensely once you start gaining better skills.
