Hard to find a job – Can you help me polish up my CV?

Dear Doc Randy…

After 5 years of bumming around the world, I’ve decided I need to get back to work.  I’ve been trying to find a suitable position , but I can’t even get those bastards at the headhunting agency to return my calls.  My buddy told the most important part of the CV is opening paragraph. Here’s what I wrote, do you think its too simple – or should I beef it up more?  Oh, and BTW, before I took off these last 5 years, I worked in IT for 10 years and have lots of certifications including the ITIL mastership.   Should I focus on that… or what? What are corporate types looking for these days anyway?    Here’s what I have so far:

Technology Visionary with an extensive background providing guidance and leadership to my clients. Background includes facilitating international cross-functional teams, analyzing business problems, identifying solutions, and recommending modifications to business process and information systems.

Best Regards,

Donny
