Can anyone build a system so i can execute my order through NinjaTrader 8 with KITE API. I am also willing to pay suitable amount for the work.

I am really comfortable working with NinjaTrader i was executing my orders manually but now i have some Algo strategies made in my NinjaTradaer and i can really use some help with it.

Why not just use Kite API with .Net custom built application. Can help you there.
