Contract for hair/makeup artist

This past weekend I went with my mother to get my hair done for the first time with her hair stylist. We were thinking of hiring her to do our hair for my wedding but I wanted to see her work first. After meeting her (and she did a wonderful job with my highlights) I feel confident in hiring her. The only problem is that she does not use contracts nor does she require a deposit and I don't think I feel comfortable taking her on her word that she'll be there when the time comes. The same goes for the makeup artist who works at the same salon. My mom just trusts her because she's been to her a bunch of times but I don't feel comfortable not having it in writing. Especially being that my wedding is on a holiday weekend. Does anyone have an example of a contract they've signed with hair/makeup artist for their wedding? Maybe I can present it to her myself and simply explain that it's not that I don't trust her, but it's common practice to protect both of us?
