Could someone mod me some stuff in Borderlands?

I was hoping for an incredibly powerful sniper rifle, preferably one that is an Orion that has damage somewhere above 6000, but if not ill take any sniper that has damage over 6000. I really need this, and my only reason that I can give you is that someone that i play with is a douche with modded guns and I want to show him he's not the ****. Also, one of those Rose Mod shields that are invincible would be great. Help me, please!
