analytics traffic fake

Hi all, I need to deliver 4,000 visitors until the end of the next week for a website I manage. The trick is traffic NEEDS to appear at google Analytics as coming from direct traffic or preferentially, Google/organic or Bing/organic. Any suggestion of tool or script, or anyone can do it? Thanks

I have tried every script program and what not I could find out there to generate fake traffic on a site. NONE of them is actually working the way they advertise it. While some can work with youtube, real sites analytics do not show ANY traffic. Google Anal;ytics seems to ignore any GET request...
