Sell two pigs right away.
Don't spend any money.
Catch one bear and put it in the storehouse. Catch the other bear when the truck is almost back.
Buy the meat slicing plant when the truck gets back, and sell the bear and two pork legs. Put the other bear in the warehouse.
When the truck gets back, upgrade the truck and the storehouse once each. Buy water. Sell one ham and one bear.
Sell one ham and one bear again.
Collect pork legs/hams until you have a total of 10. Sell your remaining pigs with whatever bears you have in the warehouse.
When the truck gets back, buy the smokehouse.
Send the plane for 5 trays. When the plane gets back, start processing your bacon through the packing plant on the right hand side of the screen. I get bored at this point and click on whichever house is closest to done, keeping an eye to make sure that it's not turning red. Ignore the bears, if you can't, sell the first packaged meat, and upgrade your storehouse one more time. Sell off the bears asap, and then buy 5 more trays. Keep processing. You should finish with 20-30 seconds to spare.
(My best time is 4:53)
