What would be a good way to drive traffic to a temporary post - job posting / classified ad?

I was wondering what would be the best way to drive traffic to a posting that will only last 30 days.  I didn't think linking would be the answer, but wanted to get opinions.

I was thinking pinging and social media (Facebook, Linkedin, Twitter)...

What would your strategy be?

Adwords.

Thanks for your response.  I guess I was looking for "free" options due to lack of a budget for adwords.

Twitter - Facebook - Leverage your social channels - Industry contacts - I think SEOMOZ may offer a jobs posting location. If not it's not a bad idea. Hope this helps.

If you can't spend money I would suggest Twitter. Ask your followers to retweet your job opening. You might also offer to write a guest post for a local blog that will get in front of a lot of your target audience.
