If it's for mobile, just browse through the apps you have and check for devs you think are a fit. Prepare a simple letter just asking for something akin to a skype meeting about your idea. You can ask if they are ready to pay you an adequate compensation in the form of a one time payment.
The idea that you get your own team with no experiance at all is ludacris. At best you can expect them paying you some bucks, a spot in the credits and if they really think you are a nice guy maybe some hourly compensation for some time they take to pick your brain about your idea (this is when you tell them stuff that has a 10℅ chance of getting into the product).
Any other path requires you either having enough ideas to make this a career (not all too uncommon), or piles of money to basically waste.
