Most good salons employ some. Full face application for photoshoot, wedding, film, night out, etc... is about $50-$75 per person in our area, depending on whether you need lashes, and $250 or so for full body application (yup, as an exmodel, I've had makeup in places we are NOT talking about. Ick. None of us in real life will EVER look like someone on screen or pages or runways. There's no way.) . The *place you're going/getting it applied for* is pretty key, because makeup changes rather drastically depending on whether you're just being seen through a lens (and what kind of lens), or in lens AND in person, or just in person.
There are also freelance makeup artists that are googleable
Whenever i want done up to the 9's I head over and use the artists my salon employs.
