Since this case involves an issue with sports betting, I don't think Casino Guru and Ask Gamblers will consider it. I remember they only handle casino disputes looking at some past cases. You will have to find someone else. Some services that were mentioned before include The Pogg, Casinomeister, and Gamblescope.
I don't know anything about the quality of neutrality of their services, though. That's something you will have to check yourself.
