how to translate "if by life or death i can protect you, i will" in sindarin?

I have decided my first tattoo would include Aragon's quote to Frodo in Sindarin script. My father wants a matching tattoo as well. The phrase is deeply important to me: I have just started reading The Fellowship of the Ring while in a mental hospital, after a terrible dip in my mental health, and that quote has been very meaningful to me. If one can also find a way to turn the sort of Anglicanized Sindarin into script, that would be even better. Thank you!!
