15 tooth + double sprockets

This should be easier to find then the double sprockets.

Well, saying you want a wheel mountable sprockets is like telling us you want an umbrella with a stick.

As you might have guessed, there are many variables about aforementioned wheel. But, using my excellent literary analysis skills, I'm going to assume you're going to be using AndyMark wheels.

Using 'small' sprockets on the AndyMark wheels can prove a bit challenging. First off, 'small' isn't very specific, but there are a couple of...regions of small.

So, from my knowledge of the Andy Mark Plaction Wheels, you can get away with a #35 chain sprocket of at least a 24 teeth without having to use the 1/4" spacers. If for some reason you need exactly 22 teeth, you're going to need to use the 1/4" space so the chain doesn't hit the wheel hub.

Any smaller than 22 teeth and you're looking at a live axle system. For this, I would recommend using the AndyMark Performance Wheels. From here, you can buy the sprockets which are hubbed with keys or hex from nearly anywhere and just slide them onto the axle.
