I am considering leaving my day job to concentrate on setting up my own business. As my business is online based, I can work from anywhere and do not need a physical office.

As such, I'm considering going travelling around South America for 6 months while I get everything set up.

Can this be done on a normal tourist visa, or would I need a work visa for each country I visit? The business will be an online service, and will initially only be available to UK based businesses.
