I am offering to develop a contact database using your Linkedin profile. Also, I will be providing you their valid e-mail addresses and before you think about accuracy of e-mail addresses then you no need to worry, I always check e-mail addresses with my tool which actually links to their LinkedIn account. So, you will be getting most updated and accurate database from me.
However, if you have any question please don't hesitate to ask me. I am always available to discuss your project and am very responsive via e-mail.
I look forward to working with you!
