Through this letter I introduce to you, myself Perry Adams. We were associated in a business deal with your company when I was working for Sussex & Co., as the Supervisor in the Sales Department.
The actual purpose of writing to you, Sir is to request for a favor. I have applied for the post of Senior Supervisor in your company and need an internal reference for the same. If you could kindly refer me to the job I will be very grateful to you. You have seen my work and I am sure you won�t regret your action.
I thank you in advance and it was a pleasure to be associated with you.
