It's a pretty bold claim to state that you can solve meta-ethics!

I think one important thing to make explicit up front is what you mean by "solving", and how we can see that your particular solution is the correct one. I mean, it might be possible to show that a system is consistent (which is non-trivial...) , maybe even that it is practical, but apart from that, I have a hard time seeing meta-ethics as a problem with a definite solution.
