re: craft leveling:

Courier leves are the cheapest way to level any crafter class (after you do your Ixali dailies, of course). It generally takes 11 HQ items to get 5 levels with courier leves. Courier ones are the ones that start in the craft's home city (Limsa for BSM, ARM and CUL. Gridania for CRP and LTW. Ul'dah for WVR, ALC, and GSM) and end in another zone (25-29: Quarrymill (I think?), 30-34: Costa del Sol (I think?) 35-39: Coerthas (Observatory), 40-44: Coerthas (Whitebrim), 45-49: Mor Dhona (St. Coinach's Find)).

You can get a crafter from level 15 to level 50 by spending ~80 leves. Have a friend (or hire someone) to craft the items for you if you want, and you can get a class all the way to 50 in as much time as it takes to teleport 160 times. (Hint: you can set the home city as your free teleport spot and the away location as favored and cut the costs down by 75%, OR you can find someone else who is also doing this, you each set one of the two spots as your free spot, you party up, and you alternate who teleports, making the ports 100% free for both of you.)

You get 12 leves a day, so this means you can get a craft from 1-50 per week for a week with minimal effort. If that's too slow for you, there are plenty of other options, but the lazy way to level your crafts is to do this for one class one day a week - should only take you a few hours. Then, when you've spent 80 leves all at once, you don't spend any until the same time the next week when they've all come back. Two months of minimal effort to get all crafts to 50 is a good deal.
