Hello, shoot me an email, my email is in my profile. I have an App Building Platform, and you can manage the app building process yourself with the help of hundreds of other programers. The basic idea is to break down the app into very small pieces, and once those pieces are built and tested, they will be assembled just as quickly and inexpensively.
I have the tooling, infra and the network of programmers, and anyone who might be interested in working with me please email me as well.
