Professional Sales Call to Potential Client

I sell verified pool owner lists built from county property records. A pool company in a specific ZIP got a sample from us with 30 prospect leads, we're talkig via email and asked us to call them. I need a confident, native English speaker to make that call, walk them through the sample, explain our pricing and agree on next steps, then send me a short summary. I'll give you the contact, the sample file and the price sheet before the call. Fixed price for one call, with more calls if it goes well.
