Hey,
It may be light work, but all work is serious work right? I assure you my sincere efforts for whatever time frame you have in mind. Since I will use the Freelancer Desktop App to track all hours I work, you can be sure I have done the work you pay for. And to prove my proficiency at the English language, apart from the Freelancer English test, I have also taken language tests from the Cambridge University and uploaded certifications of these on my portfolio.
Just let me know what ads you want clicked, on which websites and with what strategy and I'll begin work right away.
Thanks,
Bhargav
