Nope, soulbound items obviously cannot be sent back and forth. They also cannot be disenchanted by anyone else than yourself.
You do have a few options though.
If you take up enchanting on an alt and use him for only that, you'll undoubtedly have some enchanting supplies on him that you can give to a friend who enchants so that he can in turn enchant your piece. In any case, I wouldn't recommend it on anyone else than someone you trust wholeheartedly, as they could just take your supplies and run.
Still, any item that your main buys off the AH can be sent to your alt to be enchanted, then sent back to your main. If you decide to do this, keep in mind to buy your equips before you need them, since you need at least 2 hours(approx) in sending the equip both ways.
What I love about having an enchanting alt above all else is that I can simply send any uneeded greens his way that I pick up and not have to look at them anymore. It's quick and painless. After a few days, I can go check my alt and disenchant all those items at once.
Lastly, it helps your main a ton if you can make him money. : )
