Have Rigify Generate my Shoulder Rig

I have a shoulder rig I created loosely based on this video:


You can see it in action on my NSFW BlenderArtists post . No need really to click that except to get an idea of the number of bones and their interactions in the shoulder rig.

Now I want to have Rigify have a shoulder (or maybe "PecTrapLatScap"?) primitive. I don't have time/inclination to do this myself, so I'm willing to pay someone to get this ported into Rigify.

Interested? Let me know!
