pedicab like trailer for a bike
 

Does anyone know companies that sell these? i'm looking to buy a trailer that will attach to the back of my bike and will carry a couple hundred pounds.

whole rig makes more sense .. 3 wheels to gear low enough to haul 200 pounds
Just 2, means you will fall over, momentum goes to zero,
before you can get your 2nd foot on the pedal

Human Powered Machines in Eugene Oregon can build you one..
one off custom..

carrying people for hire = needing Insurance,
that is the greater challenge, an affordable policy ..

sort that out first.
