Need Link Builder! Long Term Relation!

Hi- I need quality link builder who can build links for various niche website. This is a long term project as I have lots of website and I will pay only on per link basis. Please qoute your price for per link basis. I will mostly need PR0 (but indexed in Google) links but these needs to be highly relevant to the website. PR0 - ??? PR1 - ??? PR2 - ??? Note: I am SEO myself and will count the quality links only so please do the white hat practices only while building links.
