First of all I would recommend going to a great teacher who can do what you want to do and can also teach what he does.

Here's some general advice though:

When you're practicing right hand technique have your left hand do something very simple so that you don't have to focus on it as much and look at your right hand to make sure it is moving correctly. Some things to watch out for would be the hand staying close to the strings and not using too much excess motion Then begin to use a metronome to build up the speed gradually.

Hope this helps.
