How do I cross the chasm: I'm stuck doing things that don't scale

Hi, I recently started billmarketai.com, which is a website that attempts to give users the same stock market advantages that politicians have by analyzing proposed bills and determining whether they would pass and what stocks would be affected if they do. I originally made it as an attempt to fix the problem built into apps like autopilot and dub that have a delay period while still tackling the same problem.

Initially, I had some success advertising across things like discord, twitter, and reddit. This got me to around $1k per month however each costumer I get takes a lot of effort and I want to start building advertising processes that will allow me to scale more as it's not reasonable to try to indivually recruit the thousands of customers that I would like to have.

If I want to start scaling up my revenue from a side hobby to something I can use as full time income, who has some advice for how I might go about changing my marketing plan or my revenue structure?
