I'm with a BPO and we recently launched a SME outsourcing campaign. Your project is a perfect fit for one of the services we offer.
"We are looking for Telemarketing lists of Filipino prospects who live in the USA." - We have said lists available
"we are also looking for call centers who can target international people living in the USA" - We have a number of call centers all over the Philippines, from 10 to 50 seaters, dialing US B2B and B2C campaigns.
To date, we set up 5 call centers and had 3 of them under our management consultancy service for 3 months. If you wish to start your own center rather than have another dial for you we can help you too.
