Aw, that's sweet... I'll tell YOU what. If you don't mind clones (which I'm assuming you don't, considering if one hits a seed and PID frame again and again, it's basically cloning, LOL)... I have a buddy over at serebiiforums.com who can clone for free. He's actually waiting for my Shiny Tornadus so I can get his RNGed Cresselia, cause I didn't learn about RNGing until AFTER I caught all of my D/P legendaries, LOL.
So, assuming he won't mind, I can probably get you some (if not all) of the B/W legendaries... flawless IVs, Shiny (unless they're shiny-checked), and with the most commonly used Natures (i.e. Jolly Musketeer trio, Hasty Reshiram, Lonely Zekrom, etc.) ;)
