Dear Mr. Rufus Bixby,
As you might be aware, I have recently taken up sponsorship of the Appleby Arrows. While the quidditch season has already begun, I wish to make the request that you transfer to my team as captain. A man of experience in the sport, such as yourself, would be greatly valued for the position. Please inform me of your decision as soon as possible.
From,
Mr. Ace Lukeson
