You can offer photography services to any business in the travel/tourism industry at your destination of choice. Opportunities are plentiful, whether you're selling your services or offering a trade. Going skiing in Colorado? Get in touch with local lodges about trading photography for a free stay. Vacationing in Vienna? Talk to the local tourism board about shooting a few photos for a fee. I recently made a deal like this in Cape Town shooting a month-long campaign with their tourism board, which resulted in a promotional blog post and lead to even more work. Remember that a strong portfolio goes a long way, and as it grows, so will your opportunities.
Lyn's last tip is to have your own website. "Show off your work on Instagram and Facebook, but do ensure you have a good, easy to use website too. It should have some of your best work (with lots of keywords!), any specialities, and awards/competitions you have won, and your contact details. It's too easy to get carried away, add thousands of images, and forget the basics. Keep it simple."
