Help me to be self dependent

I am a small job holder. As this job isn't fulfilling my family needs I badly need to switch to another profession by which I can fulfill my big family needs. I am doing some graphics design work from one of my friends PC. I am planning to start doing graphic designing on my own, so that I can work as a freelancer. But it's nearly impossible to buy a graphic designing computer and software by my own income. Moreover I want to enroll into online courses as well. It is my dream to be a graphic designer and better support my family.This is one of my own work.
