Although this is more in line with saving costs than making money, I think it’s a viable option, especially if you are just starting out. Not only will it allow you to travel for longer at a cheaper price, it will also allow you to grow your international portfolio, helping you grow your career through travel.
For starters, you can use established networks like Helpx, Workaway.info, and WWOOF. These are websites where you sign up to offer your help, in exchange for accommodation and food. Available in over 190 countries, you are bound to find opportunities.
You could also contact hotels, resorts and even start-ups, offering to take professional pictures in exchange for a small stipend or accommodation and food. This is how my girlfriend and I ended up staying for free in a 4 star Yoga Resort in Northern Sri Lanka! Interested in doing so? Sign up to my newsletter to get tried and tested email templates.
