Working experience

I am 22 year old graphic artist, quallified but with no experience. I would like to work as a volunteer in graphic deasign industry for the purpose gaining experience. My question is, are there any design industries willing to give young artists a chance to volunteer? Because the doors seem to be shut. In the moment, I have decided to be self employed in order to gain experience, but my concern is, I don't know if it is considered as working experience. I reallly need help.
