A couple ideas come to mind. First, you could try using a larger drill
bit and just touch it to the hole. That will put a drill bit angled
chamfer on your hole.

That works fine for countersinking a screw head in a lot of cases, but
bear in mind that a properly sharpened bit will have an angle of 135*.
Divide that in two, and you're talking about a interior angle of
67.5*, not the 30* or 45* the OP was looking for.

You could also look at counter sink bits. IDK if they come in different
sizes/angles, but it's worth looking on your next trip to the hardware
store.

There ya go. For a 30* "taper", you'll want a 60* countersink, and
for a 45* "taper", you'll want a 90*. I don't recall seeing too many
60* csks, but the 90* should be fairly common. If you can't find a
60* one, you could try using a reamer that has the correct angle.

Since the OP says he's not a woodworker, it should be pointed out that
you need to buy the countersink oversized and drill down until the
mouth of the hole is the correct width. Trying to get one that is
exactly the right size is just going to be an exercise in frustration
unless he's really lucky.

I don't see anything wrong with chucking a router bit in a drill press,
and clamping the piece down and slowly slowly lowering the bit into the
hole. Clamping the work piece down is essential, as you're trying to
drill, not route your hole.
