in lieu of buying 'spacebags' ive found garbage bags with a vacuum hose stuck into the open end sucks the air out the same way...
i like the vacuum sealers (think seal-a-meal), but tend not to buy in bulk, just buy items in a size that i will use all of before they go bad.
internet.... well i guess it depends on what you want to spend. if his clients are big accounts, you can spend as much as you want.
do a google search for 'sailnet and broadband' or 'sailnet and internet' and you will get plenty of info
