You may also want to consider Julie and Tom Wheeler with Barkbusters. www.barkbusters.com We used them for some aggressive behavioral issues with a dog. Their program with lifetime guarantee for any training issue was $400. (That was a couple years ago, but I can't imagine the price has since doubled so it would still be cheaper.)
The thing to remember with anyone at all is that you will still need to follow up and work some on your own with the dog. Anyone that claims they can come in and do the job without you having to work at it too is absolutely lying to you.
