Hello Sir,
More than having to convincing you that I am fit for the job, the idea of doing something I love and I am skillful at is what draws me towards your proposal. Although I am a writer and a part time voice-over artist, I am quite experienced in the sales and collections domain. I have worked with a BPO (american express) for about 9 years, and you can check my C.V on my linkedin profile. Given an opportunity, I assure you that you would be happy to hire me again.
