First time snake owner, looking for help!

[Kylie]

I wouldn't be able to do it, and i dont know if anyone would do it for me, she has always eaten live too and the previous owners said she has never had an issue. She probably wont go to frozen... If i were to find someone to kill them for me, what is the best way to go about doing so? ( sorry, may be a silly and gross question) i had a friend do that and im not sure how she did it, but apparently it made her snake sick and killed it?
