Our local club in in Western Oregon does an annual weeklong loop tour with sag support and camping that more than meets all the criteria and is a great bargain to boot. Last year it was a 300-mile loop in NW Oregon (plenty of mountains, coast etc.) for around $100 per person total, including campsites and all breakfasts and group campfire dinners. Only additional expenses were some lunches, snacks and alcoholic beverages. It is usually limited to less than 20 riders and you have to be a club member, but the annual fee is only $15!
