We are talking about using simple hand tools. Why would you not want to do these things yourself?? The dovetail would require some painter's Tape( that blue masking tape), a straight edge, a hacksaw, a flat file,and a Triangle file. A machinist's depth gauge will provide the straight edge, and a way to control the depth of the cut.
Take a look at Brook's tutorial at the top of this thread.
Drilling and tapping a hole requires a drill bit correctly sized for the screw size you need to use, and two taps- a standard tapered tap, and a second one which you grind off to that it has no taper and can be used to cut the threads to the bottom of the hole. A Tap Wrench will allow you to turn the taps. Some Tap cutting oil is essential to protect the threads. A straight edge, and a pencil to mark the center for the hole(s), and a center punch. These are common tools that should be in most homes already. Oh, obviously a hammer is needed to strike the center punch. Another common tool.
You can shop the discount stores to acquire most of these tools. Only the taps should cost, and standard thread size taps are still fairly cheap.
