I just discovered this guy, Peter Martin I think his name is. http://www.youtube.com/user/pianopeter#g/u He's done a number of short vids that he calls two minute jazz piano. Little pointers but really solid advice and the guy can definitely play.
Great thread by the way! I will be scouring it in more detail.
If your interested in private piano lessons or visit my home page at Piano Lessons London or alternatively visit my blog at play piano to share my thoughts on playing the piano.
I'm surprised nobody has mentioned Vika (vkgoeswild) yet! She has a very distinctive style and has arranged many covers of popular songs, mostly heavy metal. I love her "Nothing Else Matters," and "Wicked Game." I've donated to her website and gotten sheet music for several of her arrangements. They are accurate transcriptions but too danged hard!
As I mentioned, she creates mostly covers of heavy metal songs, but she'll do transcriptions for hire. This is one she did of Trevor Jones's "Last of the Mohicans," which is tremendous (listen at least until you get to the part at 3:12):
