I'm a professional artist myself.
Getting to know them and their goals.
I've been doing art on a professional level for over 10 years.
Depending on age and what their skill level is set up at. For example if you are just starting and you're new and you're just letting all the basics, prices will range 35-55$ per hour. However my advanced students are 55-85$
When I had kids and I started homeschooling when they were little.
Age ranges 4-30
I took two students out to live and feel what it was like to paint like a real impressionists in the mountains.
Make sure you find one you connect with and not just impressed with skills. Find one that helps cater to your style of art.
First they have to figure out what kind of art they like, because I would encourage you to do art that you admire.
