Hi sir/madam,
I´m Ángel Fernández, mechanical engineer, marketing specialist.
I am a marketing expert databases, and for more than 8 years I have worked databases thousands of emails with all the data. It is a laborious work, but if you assigned me the project, not only I will provide all the data, that I have people in China (Beijin), but I'll be giving freely available monthly data for you to use (for 3 months).
New and updated databases without error. You can look at the positive feedback that I have to have done this work for other employers with full warranty.
Best Regards,
Ángel Fernández
