It's not unheard of for someone to commission art assets, or set out bounties for completing difficult tasks (TTW for example). However, like Hoppyhead said, depending on what you want to do, it'll be far better for you, in the long run, to learn the skills you need.
Maybe one of us can point you in the right direction to start? What game are you intending this project for, and what's the objective?
