Inexpensive place to have charms attached to a necklace?

Can anyone recommend an inexpensive place to have someone attach charms to a necklace in West Cary, Morrisville, or East Durham? I imagine a jewelry shop might do this, but at a higher cost than I might be willing to pay. It's just some inexpensive charms that need to be attached to an inexpensive cord-like necklace. I've seen it done with pliers. Is it easy to do myself, maybe using a YouTube video for instruction? If so, what type of pliers should I buy for this and where?
