Does any one know of an complete, and accurate, list of ore vein levels. I am looking for the mining level that the ore becomes orange and minable, and the levels when it turns yellow, green, and gray for each and every ore. I have search the web for an hour and found inaccurate ones and incomplete ones.

I'm trying to find a profession combination that would both be lucrative and would also be very beneficial for both me and my guild. We are a casual raiding guild (Normal/Heroic), so will the combination of Herbalism/Enchanting be a good idea, or should I stick to 2 gathering professions?
I'm looking forward to farming gold at the start, so I'm kind of torn between enchanting or mining as my second profession. And truth be told, I'm trying to look at this situation in the long terms. Which is the reason why I'm considering switching mining with enchanting, since unlike the other professions looks extremely beneficial. And let's be real here, enchants will usually be more valuable, considering we're getting weapon enchants now.

Any advice?
Edit: Will the scrapper play a large part in the economy or should I just vendor my greens and blues?
