I purchased indian hair and wanted to highlight it with gold tones.  I don't feel comfortable attempting this myself and I'm very afraid of ruining this expensive hair.

I was interested in finding out if anyone knows where I could send the hair and get the coloring done.  I live in NY if you know of anyone who knows about someplace (local to here) other than that please advise of someone who has experience coloring extensions. What is usually the normal cost for this as well?  Thank you.
