My shop is also looking for a makeup artist. Most makeup artists will call in advance to ask if they want a makeup artist, and then I will advise them to bring some photos of the bride they have painted, and then bring their own beauty tools. Generally speaking, if the employer thinks your photo is ok and well drawn, it will also let you draw one on the spot.
The key is that you should make more wedding calls, ask more questions, or visit directly, and someone will always be interested in you. Of course, you should also have good works.
I hope my answer can help you.
