Hey!
I am not bidding on the project, just letting you know, that what you're asking for is impossible, b/c after android 4.2 an option to manipulate things like flight mode were disabled and cannot be accessed in a normal way. There are ways around that, but none of them are actually good or working well.
Just letting you know so that you don't waste your time and money. You can read about that on the internet if you want.
