Creating banners and drawings for people's advertisements

Hi, I'm Christina. My family is kinda poor, I don't have a phone yet and I'm in eighth grade. I only have like three pairs of shirts and I pair of shorts. I like shopping and going places with my friends but without money I can't do that. I honestly don't know what online job I want but I want to create banners and drawings for people who want to advertise something. I would be more than happy if you gave me this job. Thank you so much and have a great day!!!
