Easy money while traveling

A couple of sources of revenue that I use while traveling that is simple easy money.  Usually, the places I live are less than $400-300 month rent so getting $200-$300 easy money is a bonus.

First, one is a company called Vindale. They are primary a survey company and have tons of surveys to answer.  Plus the best part is they payout at $50 and I been able to get $100 a month from filling out surveys and questionnaire.  If you have a Paypal account they deposit the money via your PayPal account.  I have been using their site since 2011.  Now it does take time but pretty easy money.

Second, freelance work. Many sites offer freelance work but I rather not have a middle man so I been freelancing for many years on the side from taxes to basic accounting functions like bank reconciliations, account recon, etc. Mostly word of mouth I get referrals. When I was in the states I would go door to door to small businesses that had Quickbooks/Quicken and offer my service which worked out well for me.

Also, while traveling there are many ways to make money especially if you don't have a work visa for that particular country.  But if you do have work permit the best source of income is teaching English abroad which I know several individuals who have used Teachaway.com for job placement.

What are some ways you have made money living abroad? Would love to hear from you.
