"Cost to repaint a home interior. Typical costs per 100 square feet of floor for roller and brush application of a single coat to walls and ceilings in all rooms of an occupied dwelling, including bathrooms and closets. Add the cost of coating cabinets, trim, doors and window trim. Includes minimum surface preparation, spackle of minor defects in wallboard or plaster, masking of adjacent surfaces and priming of stained or discolored surfaces. Use these figures for preliminary estimates and to check completed bids. These estimates equate to 3 painter-hours and 1 gallon of paint per 100 square feet of floor."

I copied and pasted this from my estimating software. It's Philadelphia area rates for residential but maybe it'll get you in the ballpark.
