Amazon FBA is pretty awesome for this. You gather up all of the items you want to sell, set prices for each one, and then print shipping labels to ship them to Amazon. Everything after that is handled by Amazon (fulfillment, customer support, etc), and you are sent money. Unfortunately this only really works for items already listed on Amazon - otherwise you need to create new listings.
