When getting quotes, don't compare prices. Compare the prep work, which is very important to the painting process. You wanna make sure everything is sanded down, power washed, so that it ensures a better quality at the end. Also, look for the paint quality they use. You wanna use the highest grade of paint possible. The highest grade of paint usually lasts around 10 to 12 years, which will save a lot of money in the long run. Medium grade paint will last about eight to 10 years. They're very durable, will have a beautiful finish My recommendation is always get the highest grade of paint possible. They'll protect against the harsh environment and elements, and also make your house look beautiful.
