If you have the supply of cleaners and are just looking for demand in the service on the consumer side but don't want to spend/risk losing money, I'd recommend a commission/affiliate based marketing strategy. This is a full proof way to grow with guaranteed profit without putting dollars at risk. I would have to get more of an understanding of your app, your market, scale, etc but affiliate marketing is one of my areas of expertise and I'd be happy to chat further on how you can do this. https://clarity.fm/stevenkrinberg1/expertise/affiliate-marketing-to-grow-fast-and-profitably
