@burcinc-- Hey there, many genealogists actually start off in this field as a hobby. I have done the same. I did my bachelors in History and took up some research related jobs after college but nothing directly relating to family history and genealogy in anyway.
I became interested in it when I was researching my own family history and discovered an online study group for genealogy. I took genealogy and research courses online and started doing more research mainly for my family and sometimes friends' families. I did not make any money off of my work for a long time.
I think this profession is still very obscure and there is no clear and defined path to becoming a genealogist. I would recommend looking up genealogy online study groups as a start. It also helps to have research experience and research skills.
