We started doing that too, in addition to Google ads. We deal directly with the advertiser, self host a specific ad for them. It's MUCH more profitable than Google ads. Will phase out the Google Ads soon.
Minimal work involved. A bunch of emails back and forth, where we tell them our ad size if they provide an image. Or they provide a logo and we manually ad the text if they aren't technical enough to provide a custom image.
