Hello Zak. My name is ***** ***** I'll be assisting you with this today. To answer one of your questions, you would want to contact an Intellectual Property lawyer. They are different from other property lawyers, such as real estate, because they specialize in securing and enforcing your rights to your work, whether its something you wrote, a photo, a song, a patent, etc. In your case, however, you may not need the services of a lawyer at this stage. The fact is that you can secure your copyright - that is, your exclusive right to copy - simply by including your copyright in/on your work. In other words, include the following, for example, somewhere in/on your work: "Copyright 2016 Zakiri Lee Vivian" This puts the world on notice that this is your work and that no one else has the right to copy, sell, distribute it without your authorization.
Now, should you at some point learn that someone has, in fact, infringed your copyright, then you would need an Intellectual Property lawyer to help you enforce your rights. The lawyer would probably start by sending a "cease and desist" letter, followed, perhaps, by a demand for damages (based upon the degree of infringement).
I hope I’ve provided the information you were seeking. If you are happy with my service, please provide a rating. If not, please let me know so l can continue to help you. Thank you, ***** ***** luck with your creative work.
