Well this is a good profession and it pays quite much if I would say, but I will advise the poster to work more on creating more awareness about what he or she does, you can use the means of social media platforms and also some apps like YouTube and the likes, another way I think the person might be able to make good income from the work is to make use of freelance site to be exposed to the change of earning more, although one of the challenges you might encounter on those sites is your ratings and reviews.
