A scanner would be a good investment, because you need to provide some decent details to people trying to help.
Like, get a good simple concept drawing of a character, nude if you like, then print it off and make lots of copies, and design your characters on these sheets.
It's the only way you'll get anything done, artists work more efficiently when they know exactly what you need, and if they give you a model you don't use, then they're unlikely to give you any more. A good idea of what sort of characters you'll have in your game will really help, so I strongly suggest kicking back with some pencils and roughing out some character concepts.
