gibson guitar shops

does anybody know how I can personalise the headstock of my guitar and get rid of the original makers logo?
I need to know if there is a known company that deals in personalising guitar headstocks. ie, writing and getting rid of existing make or models.
For example if my guitar was a gibson but I would like to replace that with say, My name or a word or logo of my choice.how do i go about doing it? If anybody knows a shop or a website please please please let me know thanx!
just use some matt black spraypaint… and obliterate all dat u see..
