Best thing to do is go to body shops in your area and get estimates. Usually body shops get a lower rate than regular customers because they order so much paint at one time. It'd be kinda pointless for you to buy it yourself anyways, since you'd need someone to spray it on. Don't let anyone but a VERY good sprayer put the chameleon paint on. It's REALLY hard to spray that paint and have it look good since there are so many different layers that have to go on, and it all has to be as evenly sprayed as possible. I'd say to get your car painted with a chameleon paint, you'll want to plan on spending at LEAST $10,000 for paint, materials and labor.
