I am looking for an email list of ebook authors

I am looking for an email list of ebook authors - people who have published a book on Amazon. The list should include first name and email at least. Please note that I am looking for as comprehensive a list as possible. All the email must be valid as we are going to do a sample check before releasing the payment. Authors based in the USA, Canada or UK is preferred. With your bid please give us the price of the list along with the number of emails it contains, and indicate the last date it was updated. Info and generic email addresses are not wanted. Don’t forget to post a sample list with your bid. A milestone of $20 will be paid for your milestone sample list on the condition that 90% of the emails sent no not bounce, or pay $0.10 for each valid email in the sample.
