To improve your singing skills, it is a smart move to find a skilled voice instructor. Voice teachers are experts with years of experience and can share their knowledge with you, but at a cost!
Training with someone who is knowledgeable and has been doing this for many years will greatly increase your ability to sing and grow. If you ask anyone who has achieved a lot in any field of expertise, they will tell you that they had a mentor or teacher that helped them get there.

Many singers are vocal coaches and teach voice lessons. They are able to share their expertise in an area that is very popular with people, and it becomes part of their job.
Music is a very low-paying profession, and so many singers are trying to make it, you end up with a lot of them going into teaching. That's not necessarily good for you as a student. Why? Because teaching and doing something are two very different things. There are many teachers who don't understand healthy vocal techniques.
Someone who is classically trained will be more competent as a singer and teacher than someone who isn’t. It is in your best interests to fish in the pond that has the most fish.
You should get to know your potential teacher and feel their emotions. Ask them to sing for your benefit. Don't be offended if they refuse to sing for you. Your teacher shouldn't be able to do it. Ask them about their voice training, including where and under whom. Also, ask them about the songs they have sung over the last few years.
