Analyze My Competitor's SEO Service

Hi, I need to find out how and what software or service my competitor uses to rank his keyword! I need all his back-links and find out how he gets them. He is not using s c r a p e b **** so I wonder what is he using or what kind of service out there does such a job?? He has about 1800 back links from 500 different domains and I need those too and I wonder what software or service he uses? Need you to find out about his way of doing back links? Thanks,
