Seeking Sponsors for Player in WSOP Poker Tournament

Looking for someone to help create advertising to get sponsors for the WSOP Poker Tournament, My husband won a ticket to main event of WSOP in July 2022 by winning at a charity poker event in Chicago to help kids with cancer go to summer camp and would like to find companies and/or people to sponsor his cost for attending event and other incidentals in exchange for me wearing their gear (i.e. t-shirts, hats hoodies etc...)during the tournament. A portion of my winnings will be donated back to Camp One Chicago. We are looking for someone to do small bio to include with graphic designs for a flyer style for mail, emailing and facebook posting to get sponsor for him to go to Vegas in July. I will send you pricing and type of gear WSOP allows him to wear but we need it quickly and professionally.
