Ask some of your guildies to mail you stuff as opposed to destroying it, this should increase the volume of stuff you get to deconstruct and cost them next to nothing.
You could even agree to cover their mail cost by having them add a C.O.D. to the mails.
OP, this is a great post with spot on information. I just want to expand a little on the chest runs from item 2 above. Chests are a great way to get higher quality gear to decon, but also net you a little gold, XP, soul gems, glyphs, treasure maps, and now malachite shards. Since enchanting is by far the hardest skill to level, it's very worthwhile to use the chest glyphs to continually push that skill little by little. I opened chests for several days when I hit my Silver zone starter island to get the 1000 chest achievement. Not only did I get the achievement, I also maxed all equipment skills, collected tons of soul gems, and made a big dent in enchanting (and this was before the Inspiration was reduced). I make chests part of my routine farming runs, and use the proceeds to level alts since my main has long since maxed everything.The higher the gear the more xp you will get, so of course the goal is to get lots of high level things to deconstruct. My own craft leveling tactics have been:
1) Of course all your characters should always be sending their loot to your crafter to deconstruct, and if anyone is willing to send you their loot to deconstruct as well then that's great, but don't bother with the 0 worth stuff. You won't make as much money obviously if you're not selling anything, but the more you deconstruct the faster the craft will level, so even deconstructing white items may be worth while to you, depending on your priorities. The crafting writs are one way to help make a little money despite not selling loot, and they also give you xp.
2) chest runs - Khenarthi's Roost and Bleakrock have a lot of easily accessible chests for example, and I find I can make a run of the island and get plenty of green or blue items with less time/hassle than grinding in some dungeon or wherever and getting potions, white items, or nothing for my trouble half the time. If you can, go chest hunting with your highest character in the highest zone they can handle - I borrow my husband's veteran character and have him send me all his loot, the progress bar moves significantly with those veteran 1 and above items.
3) as mentioned trading with a crafting buddy, but if it's too much of a hassle to find someone and coordinate with them, you can always create your own crafting buddy by leveling the same craft on an alt of your own. You'll only have the mats you've gathered to work with, but you still get good xp from deconstructing items made by another of your own characters. Have your alt invest in extraction points of course, and keep the tier of materials they can work with the same as your main crafter, but you won't need to spend too many points there since all they need to do is create and deconstruct. Be sure to upgrade your passives to the next tier of materials whenever you can, but remember you'll have to have some character that's capable of gathering from the corresponding zone - whether they're good at sneaking or properly leveled - investing points that you won't be able to get materials for will just prevent you from doing writs.
3b) If you're going to be crafting things to deconstruct or doing crafting writs, you're going to need a lot of materials which means farming and refining. Style materials are what I run out of most often these days (since I'm not into stealing them and thus am not stocking up every time I go into a building anymore). Before a craft-deconstruct session, I scout out the guild stores for large stacks of style materials at 5gold per piece or less if possible, and then just use up whatever style I'm able to stock up on at the time.
4) If you have lots of gold on hand you can also buy high level stuff to deconstruct, but that's probably not going to be worth it.
