I know exactly what you are making, and unless you are going to make an absolute crapload of them I'd just cut them and bend them manually. A drill press or a simple centerpunch and hand drill, a vise, and a proper blade in a chopsaw and you are golden.
Even for dozens of them this would actually be faster. For myself, even with a shop full of proper CNC gear I'd still do it manually.
If you want to go into production that is a different matter, in which case neither your shopsmith or a cheap drill press XY table is going to cut it. If that is the case, the money will be there to justify a mill.
This sounds like a better job to just farm out for shearing/stamping though in quantity, milling is likely not the right process for these.
Try these guys, it's likely a lot easier and cheaper to get them pre-made;

If these don't work, there are other companies that get even smaller. Try Google, there are several.
