Unique visitors to 3 different websites/domains

Hello coders, I need unique visitors to 3 different websites/domains. - there is only 1 page set up on these 3 domains. (splash page) - there are no ads, so don't need to click ads. - I would like at least 50% of traffic to come from IP addresses in the North America (US/Canada) - can be more. The other 50% can be any other countries. Please let me know how many unique visitors you can bring to each site per day. I would like this traffic build-up to occur over a 30 day period. Thank you very much. Pls. let me know if you have any questions. I have lots of work, so if the project is successful, I can post new work to winning coder. :)
