Honourable sir,
I do several works in online Advertising,Sales & Marketing and i have a great experience at all.
If you give me this work i will complete this as early as possible and try my best to give effort to complete this.
I have many fan pages on different social sites(e.g. facebook,twitter,linkedln etc) with lots of fans also and thats why i can advertise your company easily.
I have a good performance in SEO too.
Regards
Khandaker
