Cost of removing original 1981 popcorn ceiling and replacing with Spantex "Orange Peel" texture

Can anyone tell me the average cost to have this done?

Original popcorn ceiling removal and spantex application with orange peel application. The job was approximately 1819 Sq Feet between 2 floors and included the kitchen, hallway, stairway, office, front and back entrance, walk in closet, 3 bathrooms, 2 bdrms, and 1 master bdrm.

We hired someone that started but we had him stop after the main floor. Long story, very disappointing unpleasant experience, and poor job. We are going to have to have some of it repaired and redone. Unfortunately he was paid in full for the work completed as we paid 50% down for the whole job.

I'm trying to decide if it will fit in the budget to have someone fix and finish it or if we should attempt to finish and fix it ourselves as we did 80% of the labor when he was working anyway. He wasn't physically equipped to do the job it turned out. We helped with 70% of the taping and plastic-ing, did 90% of the scraping and did 100% of the clean up and garbage removal. He said he could do the whole job in 4-5 days but only had half the job done in 4 days with us helping.
