Which Technique to use?

Hello,

I have been approached by a person who wants to make a series of
wine charms for a business he is starting. This is not in my scope of
work,. but I was hoping to provide enough so he would
know who to ask.

He wants probably 4 different charms with a graphic on one side and
text on the other. What sort of technique should he look into for
best rendition and cost? I was thinking cast pewter, but really have
no idea.

Thanks,
Louise
