It would be a great idea if you can get a basic, quality draw technique down before grinding it in with a lot of reps. Getting training first is a good idea. You may be able to research/watch tutorials and not do too badly. I'd caution that a significant portion of quality draw instruction is in managing holster work safely. There are some not-obvious safety issues that can arise and have to be managed when working with a holster. That's where quality in-person instruction really comes in.
Once you are satisfied that you have a safe, reasonably efficient draw to work with, there is a ton you can practice. Here's a drill to work the draw, though it isn't going to teach you how to draw in the first place:
