Name change for a non-binary college student!

Hello! My name is Emersyn and I would like to get my name changed legally! I am paying for college and living by myself and I would like to afford to get my name changed before I go into my professional career as therapist! With needing to afford to pay back my debts and saving up for hopefully getting top surgery one day, I thought I might see if I could get some help affording a name change. I looked it up and it’s about $500 ish to change it in my state with all the forms and etc so that’s where the goal is. Anything you can give is appreciated but, if not, that’s okay! I appreciate you anyway for considering me.
