well, in case this anon checks this thread again or anyone else wants to know -- i'm a jeweler and this sort of thing is not too hard to saw out of flat metal by hand. you can draw it on tracing paper and use a gluestick to stick it to the metal. thicker paper tends to misbehave.
the problem after that will be how you finish the metal, because regardless how you cut it, the edge will be rough and will need to be sanded and polished. that's a lot of work so for that reason i suggest making a .svg or vector file, extruding it (there are websites that will extrude it for you), and having it 3D printed. shapeways has some materials that will come looking polished and finished (their bronze is very nice), and if you only have to cut the shapes off of a sheet like the one you posted, that will be a lot less to have to polish.
i do still recommend using a jeweler's saw for that little bit of cutting, because metal shears will bend the edges and if you don't have an anvil or block and a mallet to flatten them back out, it's kind of a pain. I also wouldn't bend them until they snap because that'd make for a rougher edge to have to clean up.
metal is a little bitch basically. i'd get the charms printed individually if you could, that way the whole thing just exists and no cleanup/polishing is needed, bc there's a whole slew of specialty nonsense you need to get something to a mirror polish like you'd see in jewelry stores if you're doing it manually.
