Telemarketer Required - Preferably US based

I need a USA based telemarketer to do some telemarketing. We have an online auction selling machinery from a Coffee Roaster and for this, we've already sent emails to a bunch of potential leads. The people to be called are the ones who clicked on the email, so it won't be cold calling, but rather leads who might be interested. You would need to make them aware of the sale, and gauge their interest. We will provide a script which you can use (feel free to modify it a bit, but please ensure it's at least similar).

There will be 80 contacts to start off with, and we might have more once we get to gauge how this telemarketing campaign performs. If the campaign performs well, I'll be providing more contacts and the total project budget can go up to $1,000.
