I just read the whole thing, and it is amazing how fast you have been doing this, yet your attention to detail never stops.
I hope you realize that, at least to my standards, you are definitely qualified enough to at least do texturing tutorials if not modeling tutorials, as well(and probably everything else but i haven't seen it).
Im 16 right now and have been modeling in Maya (from dad's work) whenever i get the chance, and look at tutorials to figure out, step by step how to do what i want to do. I was wondering what really jumpstarted your 3d career, whether it was classes, experimenting or something like that.
