>you can use cpuminer to create some yourself.
Depends on how many you want, the dogecoin difficulty has really gone through the roof lately, and you are much much better off with a GPU. The Kh/s rating on most GPUs is much better.

The best Corei5 is going to get you about 1358 doge a day, with sounds like a lot, but it is a tiny number, 41 cents. Plus, the mining calculators are way way off. They always overestimate for me.

If you buy 1BTC from one of the established channels that you know, you can have a practically limitless supply of altcoins at cryptsy.com. That is assuming, you don't want more than 1BTC worth.
For small amounts, you could go to http://www.reddit.com/r/dogemarket, the fraud risk is not very high there. In the US, there's https://www.altquick.co/. Other than that, you need BTC/LTC first then trade on cryptsy.
