Who to develop it - do a search for app programmers. Look on the internet or yellow pages. I doubt a big company would be interested in developing a small app.
I have what i think is a great new app, but who can i trust to develop it and not steal it? Should it be a company, a contest or someone that lives around me and makes apps. I dont have much money but i know this is worth it. If anyone can point me in the right direction or help it would be appreciated. Thank you
