Targeted Traffic

I have a client that needs very specific visitors to his site I want 15 ... 30 patrons came to my site and conducted on it 5 ... 10 minutes. Be careful, the same people with the same IP should visit the site every day. Every day should be a different number of people. All people must be from Seattle, Everett and Tacoma. I have one suggestion for doing this. Place an ad in craigslist for work wanted under the Cities mentioned above and pay each person a small amount to visit the site once a day or once every two days. You would need 15 to 30 people to do this. You may have another idea. i would need to test this every day for two weeks. if it works it would be done for an indefinite amount of time. Let me know
