I have type 2 Diabetis. I'm a beader and want to make alert bracelets. I can't find low cost charms. Help.?

There is a terrible lack of bracelets and necklaces for diabetics and the charms I've seen are quite expensive. I'm looking for charms and bars for kids, women, teens and yes, men too. If anyone out there knows of someone who supplies these, please let me know. Thanks.
