I´ve written a program to automate this process. It *does* work, and I will use it to send your messages. Nobody will be capable of sending a thousand messages by hand every day for a reasonable price. That would take hours to do by hand, but it´s a breeze for me. My program keeps track of all users who were sent messages, so it´s guaranteed that no user will be sent the same message twice. I can do this for $10 per day, so my total bid is $300 for 30 days. This will get you 30,000 sent messages, and probably 20,000-25,000 unique visitors. I can also embed tracking images into each message which will allow you to track from your site how many messages are read. If you´d like to send more than 1000 per day, I can give you a better price. I can do 100,000 per day if you want.
