yes, your best bet is to vacuum seal it once, preferably twice. Keep it under 500 grams, I wouldn't send more than an ounce in one envelope. Send it USPS 2 to 3 day shipping or faster. Get it sent to a PO box. Doing this small scale, there is very little chance of being caught. If the person who ships it can, get their wife or something to do some of the shipping so its not the same person all the time.
