Generating Contact List for 1000 UK businesses

I am doing a social networking survey for my final year dissertation at Uni. However, my survey requires CEOs, CIO or any Admin staff of businesses to fill in my survey - they are hard to find. After generating mailing lists of hundreds, I find only 2 or 3 actually fill it in. Before I start giving away ipads, i thought I'd outsource this Herculean effort. I need some one to generate for me contact details for 1,000 businesses in the UK. I don't care if this is their email, Linkedin account or anything. Just so long as I can send them the URL for my web-survey
