Hard to build an internet business without an interest in some area. Do you have broadband available? I know some personal secretaries that work for bosses 1000 miles way.

Like to cook, start a sous vide business and hire the production done. Teach over the internet. Start a business of monitoring elderly residents over the internet using Skype - to insure that they take their medicine, etc. Go to school - over the internet of course - and get a degree.
