Hello,
I'll be happy to provide you with the unique impressions that you need but I would love to hear more about what kind of traffic you are looking for or where do you plan to send the traffic to.
Afterwards I can see if I can provide the right traffic that matches with your needs. (I can send you a sample of a couple thousand visitors)
My bid is for a little over $1000 because of freelancer.com charges.
If my traffic matches yours then I will be able to safely send 100K a week and increase it if you need to.
I look forward to speaking with you soon.
