If you can do all this, you're either already a developer and don't need to outsource it, or you have the ability to learn how.
That said, I did present two ideas for those who want to venture into this:
- You recognize that the "success" you have in the working app isnt actually a success and plan accordingly
- You hire someone independent who keeps the third parties honest
Another one:
- You cut corners, get a working demo, raise good VC funds and hire a well-compensated technical co-founder or founding engineer who is compensated sufficiently to be happy short term and has sufficient equity to want long term success
