Any schooling is better than none, but the
correspondence type probably won't help much
in landing a job or getting more pay.

The IBEW training is one of the best, but not
easily attained. Many community colleges have
programs. Some contractors will pay your way
if you're working for them. There are several
associations with schooling, NAHB / ABC, any contractor in your area should be able to tell you where to go. You will still have to do the hands on/ OJT.

As for getting started, look in the paper, apply for a helper or apprentice opening, show a good attitude and ask for the job.

Your goal of 4 years and getting your C-10.
You do realize thats 4 years of journey-level
experience to qualify. That 8 years to get there.

More advice: I was an electrician and wanted
to be the owner so I could make the big bucks. I found that in order to make a substantial living, the amount of work it takes will require you not to be an electrician but a business manager. I enjoyed the money but not the position.

In order to be a good business manager you do need to know the trade, however you can hire a RME to qualify your business, if thats what you're after. There are electrical contractors that have never terminated a single wire. They had a customer, which is the essential ingredient to any business and they hired an electrician with a license to qualify the business. That person is suppose to help manage the business.
