Like this man said. Or I have been able to use a plastic assortment like the one below, it should have something that will get you by temporarily

There are many good online sources but if you can do it, I would highly recommend finding a person to help with a automotive project or an internship (preferably paid) to learn. This way you will learn hands on and learn a lot more in a shorter time. Not to mention all the tips and tricks.
