If you have a background in web services, design, programming, or anything tech, a website like UpWork is a super way to find virtual work as you travel. There’s a lot of competition, but if you build up your portfolio, you can get a lot of work over time. I have a friend who gets all her freelance consulting jobs from UpWork and it pays her enough so she can keep traveling. If you don’t have tech skills, you can still start a profile and find clients for a variety of research-based and virtual assistant jobs.
Task Rabbit, Outsource.com, and Fiverr are three other sites for finding online work.
