I need 200-300 PR 5-9 backlinks, white hat only

I need 200-300 PR5+ backlinks with my anchor text to my site leaked at 7-10 a day over the span of a month. These backlinks need to be permanent i.e I don't want to see them dissapearing after a week. Please quote me on 200 and on 300. Remember - white hat only, leaked slowly over a month. If I like the monthly price I may keep an ongoing monthly relationship. Links should be exported daily in an excel file and emailed to me. Also, 50 percent will be paid when links are done, and another 50 percent, two weeks later if the links stick. If a few do not - It is not a big deal but if 50 percent of the links are removed in two weeks, we can visit a solution then.
