You need a broker to trade Bonds. I have an on-line account with a brokerage that trades bonds in companies like this. I can access a list of Bonds that they have for sale. Otherwise I have to call them to get a quote on a specific bond. Bondtraders.com used to be an open site to read bond trading quotes, but after subscribing to their free website for a short period of time, they want to talk to you to continue the service. So, to help you, I suggest that you call a bond broker.
