Hello :D
I would love to help, but I can only trade on Gen V, which would be Pokemon Black/White.
If you can trade via B/W, I can help you out :D
If not, though, what you can do is post on the Quick Trade thread in the Trade Corner asking for donation Pokemon on Gen 4/SoulSilver. Someone there is bound to help you. Let me know if you need anything else, and I'll do the best I can :)
