@OP if you look at the examples you gave for freelance sites you'll notice all of them are "specialties" but none of them are regulated. You don't find a CPA / accountant on a freelance site so you wouldn't find legal, medical or compliance people off of it. Now there might be some people that do this, or are qualified but the vast majority of people on these types of sites are more along the trade routes (design, programming etc.)
You go to the home depot parking lot for labor not for legal advise =)
Well I think the OP is looking for a job and I must say he might be looking at it in the wrong place since you'll barely find professional services related to legal counseling and also accounting services in the freelance market. These types of jobs are made available directly in their website like what I jave provided or to some profer job hunting websites like Linkedin where most professional jobs are seen. @OP if you are looking for a job related to what you have graduated in you must just go to Linkedin and no crypto-related job hunting websites.
