Two months is too short a time to build an audience. And too short a time to build a large number of good hubs.
I looked at one of your hubs and note it is very short.
Hub pages is not a magic box into which you can toss a penny and expect a dollar. You have to work to be successful. I'm under the impression you are looking for an easy way to make money.
Put effort into your writing, stick with it and you can earn some money. Writers... all artists, usually have a wide variety of outlets for their work. They don't depend on a single source of income. Just like any job you need to keep producing new work.
Hub pages can become a source of some income but you need to pursue a number of ways to make money as a writer.
Very few write a best seller. And there's a certain level of luck required. The right product at the right time in the right place.
