It took a day to prep once everything was removed. Then 1/2 a day to paint it. If you give yourself two weekends and are able to get it torn down before bed on friday you could have it done by the 2nd weekend. It takes 5 days to fully cure, so you want to let it sit for a while before putting it back together. It cost about $350 when counting Primer, Sandpaper, and two gallons of liner. The work was the tough part.
