Where can I find people to help my project

[DJ Coco]

If you want people to join your project, especially for free, you will need to show what you got.

People won't willingly invest their efforts into a project that they have no clue about how it even looks, and whether it's worthwhile of their time.
You also want to be able to show you got a sizable chunk of work done yourself, so people can be assured they won't be carrying the entire project themselves.

I highly second Vinny's suggestion to show some screenshots or videos.
