Both AwSquared and Classic Sonic have linked you to the Emulation & ROM Hacking section. There is a special section where you want to recruit new members for your hacking team, as well as in need of special help without creating a team. If you want to create a team yourself, I believe you have to be an active member for at least three months. That gives you time to organize, plot, and plan your hack, as well as planning who you *want* to hire for your hack. Planning is power! :D
Hope that helps & stuff, and welcome aboard to the community, btw! I wish you the best of luck on your hack success and I hope to see you around!
