Link Building

I need a REAL link building program in place. No Directory Submissions, No FFA's, No Article Directory Submissions, 100% Natural Inbound links from multiple C Class IP's. You must generate real links from sites that are realevant. Must be PR3 and higher. I am an seo specialist and outsourcing this so please do not bid ridiculous promises of generating massive links. I will make sure you knwo what you are doing and you need to ensure no Black Hat techniques...
