Hi,
I have gone through your following description completely and can assure you that I'm the right person for this job.
I will get you 7 unique ideas in the initial draft and one of them will be a winner.
To be on the safe side, I will even provide you unlimited revisions. However you won't be needing more than 1 or 2 rounds with me :)
Just give me a chance to amaze you with my skills. I guarantee you that you won't regret hiring me.
Regards,
Arsalan
