It depends on what you’re looking for. Some of my friends preferred to do the college research themselves but needed help with essays. So instead of hiring a college counselor, they paid for their essays to be looked over by an adult. On the other hand, some other people wanted recommendations for colleges because they were unfamiliar with the entire college process, and I know of one who paid by the hour for counseling help. Others only hired a financial counselor for help with fafsa/css options.
Since your parents probably won’t be of much help (as mine was), I recommend you look for somebody (counselor or otherwise) that can help you understand deadlines, ea/ed, financial aid packages, etc. because they’re pretty hard for a newcomer to learn by themselves.
And if you do decide to go for a counselor, ask around for recommendations and try out a couple before you decide on what’s best for you. I personally found a counselor really helpful because my parents constantly spouted incorrect information they found “online somewhere.” She helped keep me on track with constant notifications and guided me through each step in the college process. But it’s important to keep connecting with your counselor since many will be helping multiple kids and you may end up falling through the cracks.
