Re: Appointment Cancellation
Mr. Walker,
I apologize for having to cancel our appointment last Friday at the last minute. There was some urgent business at another job site, and I had to attend to it personally. I hope that we can reschedule for sometime next week.
Also, in your last e-mail you asked for some different options with regard to materials and our turn-around time. The sample books I couriered to you last week are the standard wallpapers that we use – 1.75 meter-wide, printed. But we have also started using a new process with large, floor-to-ceiling rolls that produces a papered wall without seams. The papers are the highest grade, and most have silk highlights.
As your project is a luxury apartment complex, these products may better suit your needs. This is a specialty process, requiring special equipment, and so there would be additional charges on top of our usual labor costs. Since you would be doing so many units in your building, perhaps we could offer you a discounted rate on the labor. I will discuss this possibility with our sales manager and let you know when we meet.
With regard to our turn-around time, using standard-process papers we would be able to complete the 15 units in one week. The seamless wallpaper application process makes use of a large roller mechanism; so, potentially, we could complete the work in 3 days. Again, I am sorry to cancel our appointment. Please let me know at your earliest convenience when you would like to reschedule. Thank you.
Sincerely,
Peter Lasco
