visitor 5,000/10,000 unique visitor per day

I have 2 websites that each website need 5000 unique IP visitors PER DAY for at least the next 30 days. My 1st website has alread had 3000-5000 unique visitor per day. So it need to be 8,000-10,000 per day. My 2nd website is a new website. It has about 100-200 unique visitor per day I need the traffic to start asap! I'm not looking for some plan or SEO guys telling me what packages you provise. Just tell me straight up what it will cost to get 5000+ unique visitors from UK/US per day for the next 30 days. Note that: - I will monitor the IP and geolocation of the traffic. - The traffic must be legit in the sense that it MUST stay on the site for at least 60 seconds. - There must be a CLEAR increase in the alexa ranking for my site as well. So make sure this traffic is through a browser/has alexa toolbar installed so it counts towards the alexa ranking. If you can provide this cheaply, I will continue to purchase FOREVER.
