I am disabled and my Husband came up with a brilliant idea that is not out there yet. We need someone to help turn the dream into reality.
That's great!
You know I work with a few startups, some in app development. There is a company that does apps for relatively cheap. They are however about $30k cheaper than most.
When I first got an app done, it took me so long to find a good team that I figured that time could have been used in learning. The sad thing is that app development is seen as a commodity, so I doubt you'll see 'cheap' developers... I suggest learning or networking with developers if you are comfortable with that.
Before you spend in development, analyze your idea and create simple mocks up to judge the use and feasibility of things.
My first app was done in 30 days...

Best of luck!
