This is a really good topic ;) 1. There is nothing stopping you from cold calling ad buyers and selling banner or full page mobile ads directly. It's a lot of work, lots of hustle. But the advantage is that you can microtarget to specific industries you think your users (whom you know best) will be interested in. And you learn A LOT of domain knowledge in the process. 2. Self serve text ads. I believe there's an open library for implementation on the web. But rolling your own shouldn't be onerous. Drop dead simple pricing model. Simple content moderation. And you can provide a single analytics page to buyers. They will handle their own click through analysis via embedded URL.
