Not sure if this is the place to post this, and im a bit clueless about all the factors involved or how it would work or even if it would be possible...

I have an idea for a niche flight search engine. Basically I was wondering about how much it would cost to develop it? If it was possible to be powered by the Skyscanner engine it would be ideal. i know thats not an awful lot of info but basically its a couple of ideas I have that could improve searching for a flight for a certain type of traveler easier. I know I could do with it so I'm sure there would be others that could use it
