Popcorn should only be something you eat!

Getting my house ready to sell is overwhelming! Right now I'm getting estimates for having the popcorn ceiling repaired. I've had two--one for $750 and the other for over $1,400. It seems like a big difference--but there was also a big difference in my faith in the people giving me the estimates. One came in a truck marked with the company name, etc. His estimate sheet had the company name on it along with the license number. He gave proof of licensing and a brochure about the work his company would be doing. He came through and gave a thorough description of what would be done in each room. Oh, and he took measurements! The other guy came in a van with no markings, gave an estimate on a paper with no company logo, much less license number, and showed no proof of licensing or anything else. He walked through taking no measurements and just said "I can do that". He also mentioned that he would be using a can of Kilz from Home Depot. Can you guess which one was which when it comes to price? I guess if I want the job done right, I'll have to put out over $1,400. This house better sell!!!!!!
