I'd send them to Fish307.com then. Those guys sharpen blades and are a nice bunch of people to deal with. Also check the price of replacement bladed, it might be cheaper or just about the same price for new blades as it is to have them sharpened after you figure in the shipping both ways.
That's good to hear that you had a good experience with them. I'm guessing they sent you your actual blades back. I dealt with them before and that's the level of experience I've come to expect from them.
