You can get inexpesnive Jewelers saws, from Frei and Borel, or Rio Grande. There are many more out there, but I have to go find my catalogues to tell you which ones they are. When you first use a jewlers saw, practice on a scrap piece of plastic or metal. Get saw blades a little bigger than you would think, they are less prone to breaking. Also make sure you have some jewlers wax to occasionally run the blade over so it will not break. Saw a little bigger, outside your markings. Then go back with a good small file like the ones the jewelers use (#2) and do the finish filing. If you have a straight edge, you can do this by placing sand paper on flat surface then running the edge back and forth over it until it is at the right markings. It gives a very clean perfectly straight edge. We use to cut out the pattern on a piece of self adhesive shelf paper. Stuck it on the piece we were making and cut it out that way. Painting it on, can leave wavy lines. With the patern piece you can get very precise. If you buy a rawhide mallet (good investment for all sorts of things). take the thing outside when you get and beat a cement step up with it. It needs to have the leather broken in. When it comes it is so stiff it could pass for a metal hammer. Do not worry that it will look all frayed and deterioated from what it was when it arrived. The softer the actual surface the better. The weight of the hammer and the rest of it is solid. This helps to keep from marring the surface. A scribe is good for marking where you want to drill. Then take a nail, and tap it on the mark to leave a bit deeper indent. It makes drilling little or even bigger holes much easier. If you work the piece too much, and have more work to do, it becomes what is known as work hardened. You will need to anneal it again before you do much more work. That can be done with a little hand held propane torch. Put the metal piece on some bricks on a surface that is impervious to high heat. heat up the metal piece until it just begins to glow. Have an old crock pot ready. A good substitute for the pickle compound (that is what you do to the metal to clean it off after annealing) is to get some swimming pool acid. Make a dilute solution of this, about 25% acid to 75% water. But add the acid to the water. Set the crock pot on high and let it warm up. After you anneal the metal, use tongs and either wait until it is cooled, or rinse it under water before you put it in the pickle pot (crock pot). after it has set in the pot for several minutes, use the tongs to take it out. You can finish cleaning it with 409 or fantastic. They work marvelously on metals. Ohhh and the files I would get are a half round, flat, and maybe a full round one to do those spaces you need a special file for.
