You get major suppliers once you reach a high enough reputatio level. It will tell you when you\'ve upgraded your reputation level if you press L2 (PS2). Then just go to your mansion and go in your office. It will say level upgraded and then tell you whether you\'ve unlocked the big suppliers or not. I think you have to be either a level 3 or 4 to unlock the suppliers, I don\'t know. I\'m a level 5 and I have them, and I\'m pretty sure I had them at level 4.
