My advice whenever working with any software related company always have an external product manager or product owner.
Ask the product manager to map out an MVP and define key metrics and measure performance. Remember for you it’s was product and helping people but for them it’s just another project. Divide the whole project into milestones, keep track of these milestones.
You would have to to outsource until unless you are a good developer yourself.
If you want to give it a try go for a no code tool and see for yourself. Its harder then it seems.
