I have a Galaxy S3.

When I click on a contacts name, there is a green phone icon on the left and a brown envelope icon on the right.

When I click the brown envelope icon, it sends me to Skype. However, I am intending to send them a text message. I have no way of sending my contacts text messages.

I have found task manager in the applications manager and cleared the data and cache. Under defaults it says "none found"

Welcome to the forums. Try this: Settings>Apps>skype>click clear defaults. I am guessing, perhaps you clicked Always for another command, but Skype took that for everything.
