Every time I know somebody is in the market, I get them a copy of What Color is Your Parachute. It gets updated every year. It'll help with finding a targeted position that wants your skills.

I hate working for big corporations. Recruiters will only find you the worst contract jobs. Finding where the small businesses are looking is something that shook out of the book for me. The methods you're using are all the methods that the large companies want you to use and you'll almost always get filtered out. Find places where small companies are looking for your specific skills. They don't want to be awash in dozens of resumes anymore that you want to be blasting your resume out there to dozens of systems that are only there to filter you out. The places might be a niche job posting website, might mean an industry event, etc.
