links, directories & articles

I am looking for 1-) 90 PR4 opermenant links per month, every month. 2-) submit 8 articles per month, every month. 3-) directory submission to 100 successful directory submissions that are of not less than PR4. I want someone who is punctual and stick to his word. All links are to be from computer related websites. I want a break down of the cost for each point. No time wasters.
