Hi [Owner's name],
 
We had been watching [Seller's domain] for a while with a business intent 
in mind for the domain, but might be willing to give it up for the right 
price.  How much can you offer us?
 
Thank you,
[Seller's name]

[Seller's name],
 
Thanks for your response.
 
I a small roofing contractor in the Portland, Oregon area. I am not sure 
of the importance / value of a .com domain for a local area contractor. 
I was hoping for something around $100.oo
 
Thanks for your time and consideration,
[Owner's name]

Hi [Owner's name],
 
We appreciate the offer, but paying $100 for a domain of 
[Seller's domain]'s quality, even during these financially difficult times, 
would be akin to paying $400 for an upper Manhattan apartment.  Flipping 
through NameMedia (Buy / Domains / com), a leading domain retailer which 
targets small businesses such as yours, I managed to pull up the 
following collection of domain listings ending in -Roofing:
 
 * Wright / Roofing / com - $588
 * Dynamic / Roofing / com - $1488
 * Keystone / Roofing / com - $1888
 * TLC / Roofing / com - $2888
 * NJ / Roofing / com - $3788
 
-Roofing domains tend to sell to small business owners for low 
four-figures.  But since you appear to represent the smallest type of 
business of all (one person), we are willing to offer you [Seller's domain]
for $450.  Despite your business's local nature, I would be very 
surprised if you could not manage to recoup that $450 overhead within a 
few months of your purchase; after all, owning [Seller's domain] would 
boost your site to the #1 Google search result for "[Seller's domain's keywords]" -- an 
expression which (without quotes) is Google-searched 140 times per month 
-- within 3 weeks.
 
Let me know your thoughts.
 
Warm regards,
[Seller's name]
