Looking for Beer Company to Sponsor an online Esports Tournament

Hello, I am apart of an online amateur league for a video game called "League of Legends". The league is called , "Beer League", so I think it'd be really cool to get a beer company to sponsor an upcoming tournament. I'm currently working on creating a 1-Day tournament between the existing teams for a prize pool of $500. Does anyone know of any small beer companies that might be interested in being our sponsor?

Players are all across the US, but we have a heavy concentration in Texas (Houston, Dallas, Austin) and Minnesota.
