Looking for 2 Tradebacks (Trusted Users Only)!

[d/e] I need 2 tradebacks to evolve my Poliwhirl into a Politoed and my Gurdurr into a Conkeldurr. I will supply my own item for Politoed, obviously. Looking for trusted users only, so I'm sorry if I don't choose you. Collateral would be welcomed, but not needed. Thanks!
