Interesting topic, if you are looking at this kind of help, I hope you choose the right one.  Realizing that some of those that are offering training are attempting to secure money or fame for their experience.  There are no hidden secrets to success.  Personally, I found that most target shooters are glad to share everything they know with you, and especially those things that worked for them.  A combination of ideas may require sorting of the things you believe might work for you.  But this combination of ideas is much better than any one person’s opinion.  And it is free.  There are a thousand things that contribute to winning any target competition, difficult to cover them all other than the basics in a set down training course.  When looking for help, take notes, but understand why they are making those suggestions.  Everything has a purpose and all are critical to your ability to make accuracy improvements.
My objection to training experts is that everything is absolute.  Not really true.  If it were absolute they would win every time.  Most of the training experts compete much more than the average person.  Percentages prevail.  The more one shoots the better chance of improving averages.  One thing you might experience from a training class is those things you just didn’t think of.
Now in view of all this, training classes can introduce you to the basics.  The problem begins when more is required than those basics.  The more you compete and the experience gained will result in more questions.  The smarter you get, the less you know, it is a never-ending task.  So much can be learned by going to target matches. If you can’t find anyone to help, they are not the kind of help you need anyway.  The best ones are those that have the time and patients to share plus realizing they are an important contributor to this sport. 
Here are my rules: Watch, Ask, Listen, Understand, Apply, Practice, and fix what doesn’t work for you.  There’s a lot of good shooters and they are easy to find.
