If you need a fast international door-to-door shipping by air , my experience may help. I learnt this agent called contour-usa from mitbbs last summer. I had 5 mid-large suitecases, total 20cft ~ 340 lbs, so I didn't ask for the packing material from them. Most of them are clothes, shoes, books, but no electronics. One small trick to avoid unnecessary customer duty is to put a low declaration value, for insurance as well. I got a quota of $1000 +75 insurance, (asked for $1200 and offered $200 discount). It took 4 day from pickup from NYC to deliver to Beijing, and another 3 day to clear from Beijing Duty, where Fedex China contacted me and picked up some clearance doc from Beijing. Overall it is a pleasant experience within budget. Hope it helps.
