How do i get a bracelet with my name on it?

I've seen this boy who was wearing a bracelet which had his nick name on it. I want one because i thought it was really cool having your nick name on a a bracelet instead of a name of a brand sch as d&g or dkny. I really want one but i dont no how to get them done and where to get them from so can any tell me and can u also tell me how much they are going to be in the UK. I cant ask that boy as i dont get on with him and don't talk to him. His was a black band with his nick name on it it in silver crystal kind of letters, i dont no if it was real crystal but i dont care i just want one but i dont want the band to be black i want one with a silver chain and my name on it, please help, thank you!!!
