I'm a newb, but why keep a gathering profession at that level when one loot item could fetch you enough gold to buy plenty of mats to get you going, and then you can just sell the products for more mats? I'm loving LW right now because I got the Gem Studded Leather Belt pattern, and the belt is fetching around 42 gold on my server until some idiot ruins the market for it. I think I had to be at skill level 200 for it which you should have the assets to breeze through having gathered til lvl 80. That's just an example, not a great one either with the gem cost, but, lots of stuff past 150 gives a great profit margin. Auctioneer is saving me from selling so many obscure items used in LW such as potions or long tail feathers, ect. and knowing what to bank has saved me a ton. Getting Auctioneer if you don't have it will also help you make the best Enchanting decisions because it tells you the reagent you will get from disenchanting and helps you decide if you'd rather sell the item.
Now this is of course based on the idea you are switching to make money. You could have a different reason. And disenchanting a green some idiot put up on AH for 20s for mats is fun for me. My LW is still a skinner at lvl 35, but not for long. My Enchanter is lvl 20 or so and she is rich. I'm solo PVE and casual right now so I'm not pissing off a guild hanging out at the AH bottomscanning for greens, and the PVP or raid types are going to have a totally different perspective.
