Hi adamac41,
Hope you are doing well. I have reviewed the requirements and would like to offer my service.
The best source(s) to find these details are LinkedIn and Jigsaw. All the companies/Professionals have a profile on LinkeIn and since LinkedIn is also used by recruiters, all the professionals/Companies using LinkedIn keep their profiles current, I have done many such projects using LinkedIn and Jigsaw. Through LinkedIn we can find who's who in the company,though email research has to do be done via google.
I share samples with you from the previous assignments.
Looking forward to hear from you.
best,
ankur
