A full size sectional...3 seats + 2 seats + wedge starts at $250 for me...i will charge more if its hammered.17 per lf. Most sectionals are between 17 and 21 linear feet. So 289-357 is a good estimate for what we charge.
No good deed goes unpunished. Usually it is customer like this that will complain about every single little thing I would walk away and feel good about myself rather than slave on someone's stuff for very little or no pay.
