Makeup?

So I’m currently 18. I have one son and another baby on the way. Well I don’t have a job right now and I want to help in some way or another for bills so my husband doesn’t have to do it all. Well I’m kind of considering starting a in house makeup business? Something little like only doing close family and friends and maybe building it from there. I’ve always had the talent for makeup and hair. And I’ve done tons of peoples weddings hair and makeup. Is there anything illegal in this aspect doing it from home? And not calling my self a professional? Can I get arrested or anything? Also what do you guys think? Would this be possible? Here are some pictures of some on my self.
