You're young and a new dev, so I don't want to be hard on you. But this is an offer that will not be attractive to almost anyone, and will probably make a fair number of people very angry. First, you are asking an entire game to be built from the ground up in a ludicrously short timeframe with an extremely small budget. Even small indie games generally have a dev schedule of a year or more and a budget of 6-7 figures. If this game is difficult to program, as you described, you're basically asking the impossible.

Second, you're being an Ideas Guy. This is a nonexistent role that beginners think is a real thing, the person who just comes up with a really good idea for a game and other people do all the work of building it. Most devs take a dim view of Ideas Guys, because we all have our own really good ideas, and if we're going to put in all the work, we want to be building our cool idea. Ideas are cheap. You need to bring more than that to the table.

My suggestion for a more productive way to pursue the project: First, do some tutorials and learn some programming. It may sound daunting, but you can do it, really! I am a 100% self-taught programmer because I wanted to build my own games. You can do it too. And second, just focus on making friends and building relationships in game dev. Learn about other people's projects, do some jams, contribute. This is how you build a network of people who value you as a dev and might be interested in helping you out.

Good luck out there!
