There are people who are formally trained and specialize in fitting customers with ski and snowboard boots. They usually own or manage local sports shops. They're called bootfitters and they can work wonders.
Try googling for one in your area. You may not need any custom work done, but they'll work with you and offer invaluable advice.
EDIT: Also seriously consider Focus Boa lacing. My Vans Cirro are an example, although it's gotten much more popular in the past few years, so you have quite a wide choice of boots with Boa now.
