I can message your competition's followers (all of them) in a @reply and tell them about your site. What I can do is take your competitions' followers and put them into a database. Then I can @reply them (send a message) with your site/link or whichever you want it to say to them. I have a bunch of names that I use so I will give you the name of the account and you can live watch it Tweet thousands of people. Being that we don't want to come off as spammy, I can contact around 1,200+ people without it being spammy/over-the-top/risking getting banned by Twitter. I have a lot of long term clients from DigitalPoint and currently run it for 11+people daily. For instance I am currently running it for a guy and his #1 competition has a Twitter account of 158,000 followers. I am sending a message to every single one of them and that will take roughly 150 days to do considering I can message 1200-1500 a day. Since my computer is on 24/7 messaging people (which you can watch it do live anytime of the day, new messages go out every 1-4 minutes, I charge $8 per day (roughly 8 dollars per 24 hours or 8 dollars per 1200 people messaged) PM me if you want this.
