I typically don’t freelance unless it’s for family or friends etc! But I have many friends that do and it’s honestly all about networking. Create a Facebook page, Instagram, Youtube, Twitter, etc to display your work! Build a portfolio. Let as many people as you can know what you do and soon enough the word will spread. :)
Also, try working for a cosmetic store or counter. It allows you to practice working on clients and also gives you great connections in the beauty world!
Good luck xo
