Telemarket for me

I am looking for vendors who can deliver me leads on daily basis for B2B whitepaper campaigns for different regions of the world, like NA (North America), EMEA, APAC etc. I will pay on CPL basis not for hourly basis, and payment time will be different from campaign to campaign basis. I will need both MQL and SQL leads. Script, Suppression list and RPF will be provided by me. A sample script is added for the campaign that I am outsourcing now. Other campaign script will be similar to this, and CPL will be decided and agreed with other terms before actually outsourcing the campaign. I have multiple campaign, so this will be ongoing process. For me Quality of leads and Punctuality of delivery is most important.
