Young Starter

I’m planning on getting married shortly and next year i will be eighteen. I will take my A+ test later this year. I’m searching for a career as a plain pc repair guy. I’ve submitted applications but with no experience your not well wanted. I’ve been thinking about just Volunteering at a pc shop.? How is the field of Pc/hardware? What are my chances of getting a job, or better a career? I enjoy troubleshooting. and am more talented than most Tech guys i’ve seen.
