Good minecraft server list Sponsor

Hello PMC, I am wondering where is a good place to have a server sponsored for things like websites? I have recently gained about $100 in donations and want to use some of that for more advertising for the server. I have checked a few sites but the "Bidding" and stuff is ridiculous. I see the top 10 bids are like 300$+, any site that's still fairly popular and cheaper? Thanks for the help!
