Need 20 Pr3 One way permanent Back links

My Budget is US$75 for this. I need 20 Pr3 Permanent one way back links from Software , download software related sites. Links must not be from Directories, forums, Article sites, link firm and blogs. Link must be from static non flash site. Link must be from the page which has Pr3, not main sites PR3. No more than 30 outbound links from the page accepted Link must be visible and should follow white hat techniques Link must be cached by google and website must have already cached by google. If link does not cache by google crawler you have to replace that link with same PR from different site. I have many other links which need this service. If you can complete it properly will get more jobs soon. happy bidding
