shipping car from usa to colombia

Hello everyone!

I contacted Wallenius Wilhelmsen Logistics and requested a quote using RORO service from Florida to Colombia. Their fee was very affordable ($850) but they told me that I need a Freight Forwarder. My question is why this is needed, how do I hire a Freight Forwarder and how much will it cost me.

Any help will be greatly appreciated!
 

Looking for an  agent to ship my vehicle from the USA preferably Texas (as i am in California) to Colombia. Is it posible to hire an agent in the USA with contacts in South America to handle all the work ?  I am looking to drive around South America starting in Colombia and ending up in Brazil. Not interested in driving all the way down through central america then shipping from pananma on. Just want to focus on south america. Please respond with any advice or recomended agents.
