Just wanted to give a shout out to this legend grind service I just used. They streamed the process for me and answered all my questions via Skype quickly. Yes I have 0 rep here but take a second to look at his ebay account, that will back up what I'm saying. If you are considering a service like this I strongly recommend checking him out before committing.
Here is the ebay link, see the feedback here.
