In my opinion that's a bad idea. You'll have 2 crafting professions, and no gathering professions. It will cost you a load to level alchemy, and you'll be needing to buy all of your mats for both professions.
Honestly, if you want a profession that makes money, Mining is the way to go. Skinning is also pretty good on my server, and it will save you spending hours running around in your lowbie zones finding ore motes.
The fastest way to make money is to just finish up all of your remaining quests. Most should reward you between 5-10 gold, the big quests 15 gold upwards.
