Five Star Range Repair/Service

I have a Five Star Range in my house that has received ALOT of love over the years. Recently the last of the igniters have died and it could probably use an overall check up/servicing (not to mention a professional cleaning)!

Anyone with a similar range (BlueStar, Viking etc) have any recommendations for someone to service it?

FiveStar has been less than helpful trying to get a recommendation.
