A polyglot is someone who can understand and speak many languages. This term can also be used to describe the hobby of people who know several languages. You may use these skills to start a small business by offering translation services.
Online platforms like Upwork and Flexjobs can be used to find clients and build up the portfolio over time. When you get a bid from a lot of businesses, you can recruit more staff to provide your language translation services. Projects like CPEC and many other multinationals, they also need such a person to deal with local people. You can also offer services for writing the application and document in local languages.
Multinational companies operating in cities such as Gilgit, Chitral, Fata, and other rural areas always need of such people. If you can understand more than one language, then sell your skills and earn money.
Thank you and best of luck 🙂
