Hiring an artist to help make my landing page images "better"

Currently my artwork is all stock drawings from envato/freepik, and I don't like it. I want some more custom stuff. My services include streaming (twitch, youtube, facebook gaming, etc), youtube, esports, and twitter. I want to see some of your artistic styles before I declare "what" exactly I want, because I'm floating a lot of ideas right now. I will share the website link to bidders that mention they "know what streaming is", because i find a lot of people don't know what that means. Artwork will likely be 5-10 "pieces" of various context without tremendous detail, however my maximum budget is around $500 USD
