I know that Gadget Co in Tulsa does a knife sharpening service. I've been happy with the results. I'm not sure if they can hone straight razors; give them a call and ask.
There are mail-order places that will sharpen your razor if you mail it in. This one is $25.
Carwins shave shop in okc does it, but there are plenty of places online you can send it out to. Straight razor designs out of Missouri did a great job on mine
