What are the uses for pygmy goats?

So my mom and I are starting sort of a back yard urban farm-type thing with chickens, a duck, a beehive, and hopefully, two pygmy goats. But my mother only wants to keep pygmy goats if we can find a way for them to earn their keep. We live in Seattle, so it’s definitely the city, but we’ve had a sort of urban farm before, just never with goats or a beehive. Any idea of what I could convince her with?

You can use them to keep brush nibbled back on your property, or, I suppose you could raise kids and sell them. Perhaps if you have enough little farm critters, you could have an informal petting zoo of sorts? I don’t believe it’s practical to milk them, although I suppose it could be done.
