You are definitely wise to seek help! The best work often happens out in the open with groups of people working together to help each other!
My personal belief is that the IETF would be one of the best sources for places for you to go to find like-minded people to work on this sort of thing! This forum is oriented towards helping people use GitHub effectively as a tool to manage their projects. Because of that focus, it is less likely that you will find as many people here interested in developing networking protocols than in a large open international community of network designers.
If you wait until you have a perfectly finished product before revealing it, you are unlikely to ever finish it! If you are willing to communicate politely and respectfully, and to listen and take into account feedback you get from others, you can have a great experience collaborating with others on great ideas that you have. As they say, release early, release often!
