I've checked your posts on the Help Wanted forum and, yes, you do have a big task ahead as you basically need a whole studio!
Obviously you'll have to devote a lot of your time to recruitment. I don't know how much you're doing already but maybe finding the right person and asking them individually is one idea. Checking out game jams, for instance, is a good way to find people who want to get into game dev more seriously,
You might also need to reduce the scope of your project and work with you've got or can realistically get (for instance, can the game designer do the level design and UI too? Do you really need so many artists? Can you get the audio you want from open source assets?.
Anyway, good luck and hope you get the game you want!
