Slugbugg, I could possibly help you out with your tooling needs. I own a grinding co. that sharpens metal cutting tools for the machining industries. I always have some used tooling laying around that I would be happy to part with for shipping cost. I can also sharpen the tooling you have.
Carbon fiber and fiberglass are abrasive materials and do eat up endmills quickly. Carbide will last a bit longer and TiN or TiCN coated mills will last even longer, but as you know cost much more.
I would be happy to donate my services for the cause.
