Where can I get denominations put on my chips?

[MookieBlaylock]

When I first bought my chips about a year and a half ago I didnt know what type of limits my friends and I would be playing so I did not get denominations put on them. Now we have a regular 1-2 hold 'em game and I would like to add them. So I have 2 questions:

1. Do places put denominations/logos on chips that have been used (very little wear and tear)?

2. Where is a good place to take them in Vegas, for both quality and price?

Thanks in advance!
