From: David Johnson
To: Eric Anderson
Hello, Eric. Thanks for your email. First, I'd like to say how pleased I was to hear that your company accepted our bid to design your new ad campaign. We will be using a subcontractor to handle all of the printing for this campaign, including pamphlets and signs. In the past, we have used a company called Quality Press. It is a subsidiary of Printco, and is quite reliable. I will send you a list of their estimated costs, along with a spreadsheet outlining the revision to our proposed schedule.
Also, I have assigned one of our staff members to assemble a task for that will be in charge of consumer research for this project. Her name is Karen Lopez and she's a specialist in market trends. She will be mailing you a packet containing a summary of our preliminary market research later today.
