Telemarketing Technology Companies

I have a list of USA small technology/computer companies (company name/contact/telephone). I want these contacts called to see if they would like to subscribe to my free newsletter. I already have a script written. I would like this job to be assigned to one person whom I could train and liaise with. I do not want this job spread out amongst numerous individuals in the one company. I want the person to be experienced at calling, to be very polite and warm and have an excellent command of English. I would like to do an initial test run of 500 companies and assuming that goes well, then there would be 1000's more. When quoting, please quote an hourly rate which includes the cost of the phone calls. Please also provide references. Thank you
