I need a database of NRIs(Non residential Indians) who are staying in US,Canada and UAE.
Also, email should be valid,no duplicates and i need a proof for the validity of these email ids.
I need these for marketing of my friend's property/real estate business.
I will prefer already available one.
Also let me know , how much time it will take if it has to be done from scratch and what will be your source to get the data.
Thanks and regards,
