Twitter Followers

Im looking for 500K twitter followers. Followers must be REAL users. Meaning I need followers that tweet and will retweet my tweets. I've used other services in past and the followers don't ever retweet or interact. Can you provide real followers that will interact and retweet? I understand not all followers will retweet and interact, but I expect atleast 25% of the 500K to retweet and interact or I will consider the service as not delivered. If you can't provide 500K followers, then please feel free to bid and specify how many you can provide. The most important part of this job is providing REAL followers that will retweet and interact or the job will NOT be complete.
