Cost of ripping off roof, raising first floor ceiling?

My cabin needs a remodel. Appr 840 sq ft on first floor. Need to raise ceiling by 1' (outside is cedar siding, not shingles) & "re-do" second floor under the roof (don't know correct terminology - can't see a second floor from street but it's under there!). Want "basic" finish - nice sheetrocked, painted walls/ carpeted floors/can ceiling light fixtures/but DO want upgraded architectural roof shingles, not just vanilla asphalt type. No fancy roof lines - just a rectangular base - although 2 dormers in the front. I'm GUESSING finished square footage of 2 new bedrooms with closets/1 bath - shower only/some unfinished storage under roof to be around 650 square feet +/-. No prior bath upstairs - will need to run "pipes" & downstairs bath isn't directly beneath but maybe need to rethink location of upstairs bath so as to utilize downstairs config. Pacific NW - not year around resident. ANY idea - ballpark - as to what to expect PSF for this before I get my heart set on it?
