Dear Sir,
I am confident that I can provide an excellent result for the task at hand within the required time framework.
To facilitate matters I am going to split the list equally (if possible), thus providing you with a balanced result (i.e. 1,500 emails for the Australian part and the rest will be dedicated to the American part).
Should you be interested in the bid, please contact me in order to start immediately.
Looking forward for your reply,
Kindest regards,
Cristina Chintada
