I think you got a good price. You could probably go cheaper on Aloha or AmTrans, but no miles on the latter. That's about as cheap as UA gets to Hawaii. I was looking for something for Hawaii on UA in July and everything was pricing out much higher - around $650. I'll have to look again.
Be warned though it's tough to upgrade to Hawaii with certs as a Premier.
