If you want to get a response, you will need to provide more information.
What exactly is the game concept?
What skills do you bring to the table? eg. Programming (which langauge / tools?), art, music, marketing...
...and by extension, what skills are you looking for in others?
Show us some of your previous work - whether that's games you've made, an art portfolio, or a kickstarter you've run.
Sell yourself! Convince us that this opportunity to work with you, is too good to refuse.
Designing a game is the easy part - and for most of us, the fun part (I guess that's partly why game jams are so popular).
If you aren't able to contribute some other valuable skills as well, you are essentially just asking someone else to make your game for you, and noone is going to do that unless they're being paid a fair amount.
