Coaching Recommendation

Hi Guys,
I have been riding for a few years now, mainly All Mountain stuff and some Downhill on the North side and I've hit a bit of a wall when it comes to improving my skills. I have raced the last couple of Roller Coaster Gravity Enduro races and was a bit disappointed in my times.

Anyways, like a lot of others, I am self taught and I think that is where the problem is. So I've decide to get some coaching and was wondering if anyone can give me some recommendations for private coaching in Sydney. Any help is much appreciated.

Chris
