There you go! Dedicate as much free time as you have to studying to get an A+ Certification, then start searching around for local IT/Helpdesk jobs. Once you’re in and get some experience, there is all sorts of room for promotion. It all depends on the time and effort you put into it.
As far as what/where to study, there are a ton of resources out there. Professor Messer has a whole series of totally free videos for not only A+ certification, but most of the other major certifications as well. You should also pick up this book as it covers just everything you’ll need to know for the exam plus a lot more.
