HI..

Very simple and very brief...
I suppose you want someone to help you on execution but you don't have the funding.

You have two options:-
. ether get funding : check venture capitals, seed investors, angel investors , incubators ...etc
Also, something like kickstarter can help you raise funds..

And then hire the candidates you like.

OR the shorter part..
Hire people that work for EQUITY instead of money . Something like https://angel.co/ has multiple similar jobs, and you can also get a co-founder there as well..

One last option, go to recruitment offices in universities / colleges near by, and you they can help you find candidates that are interested to join. Again, better have people work for equity. If you are looking for someone to work for free , will be difficult to find good candidates. But lots of newly , or close to graduation students have entrepreneurial passion and willing to join some new startup that is willing to grow and grow with it. This is the type of students / fresh grads that you will be looking for.

Good Luck !
