I just met a Mexican guy the other day who works for one. But forgot the name of the place. But Dude, use Yelp search, and look for companies that are close to your home, or close to your work place, that have a lot of reviews, and a good 3.5 or higher average. If they have more reviews the average will be more important.
And get it all in writing...What ever is written on the paperwork is what they are going to do for the money. Anything that any guy tells you are just words, and not part of the contract. They just had a Judge Judy case about what was promised was not what was on the written contract.
What is the scope of work you want done ? What kind of paint, what are you paying for in terms of prep work. It is not cheap.
