Question about Zazzle and working at home?

[Sparrow]

I made a Zazzle account a couple months back. Didn't sell anything. Then came up with a plan, I'll make posters and put them around town. Sold nothing. :| Actually the poster in the pet shop is gone. XD Anyway, I've made one sale from Zazzle so far. However it was a side shop I never advertized. My question is, is there anything I can do to make it so people can find my shop? I don't Facebook, Myspace, Twitter, or any other online...Chat....Thingy. I'd just like a way to get a little money in for while I'm getting my license, so I may then find a job. On another note, are there any other things I can do from home to bring in some income while I learn? I make art, I don't think I'm that good, but people tell me that I should pursue an art involved career. Anything that could possibly help me get some income would be great. Thank you.
Questions:
1: How do I get people to find my Zazzle when I don't blog.
2: What types of things can I do from home to get income?
3: Do graphic artists make enough money to not need a second job?
