Cost/Process for changing flat ceilings to vaulted

[David A.]

Hey all! I'm hopefully gearing up to buy this really cute 1bedroom cabin in the woods in Connecticut, and am excited to start demo-ing. The roof line looks like this: _/\_, and the building is 20x30 (10x20 on the flat roof line to one side being bedroom/bathroom, and then 20x20 for the /\_ roofline being the living area with the kitchen and dining area under the flat part of it. The entire ceiling inside is just one flat ceiling. 

The ceiling is super wonky and will need to be taken down to studs to make sure it's structurally sound (plus the roof needs to be replaced), so I'm wondering what the process (and cost) of turning the entire thing into a vaulted ceiling would look like. There will need to be structural beams 10 feet in from either side where the flat part of the roof meets the ends of the gabled part, but I would love to do like a shiplap vaulted ceiling - I think it would really add to the 'cabin in the woods' charm. 

I've been trying to learn what the process looks like for this and not seeing a ton of great videos/articles, so as always, I turn to BP :) Would love to hear thoughts, considerations, etc. - I'm pretty confident that the aesthetic change would significantly heighten the appeal and consequent value in the home, but I'm not too confident that this is something I can realistically do myself, so curious to also learn about pricing.
