Patron Saint Pendant?

I want a pendant that represents a saint but whenever I search for different saints and their meanings the sites aren't very helpful. I'm not Catholic I'm a Christian but I still want a necklace because I think ,the idea of a saint with a specific job looking after me is beautiful. So if you know of any please list the saints and their meanings or a site that will have them listed. Thanks!! If you know of any stores where I could buy the necklace that would be awesome too.
