1) It depends on the service/product. I have no research behind this or theories, I just put up what I think will look nice. The key is that 90% of my customers do not know how to edit a website or manage a domain or anything.
2) As for what pitch I use, this is a good question, I try to increase the value of the domain to the buyer with the memorability of the domain. For example (random example) poolcleaningmiami.com is memorable and good for billboards and business cards. If the business is called +"mikes pool cleaning" then my domain name is easier to remember + my template is prettier + it can redirect to his current site.
3) Website + Domain is $399-499. I do not sell in the 1000$+ region, its a waste of time compared to what I make with lower sales. I automate most of my work and I prefer working hard on websites than working hard on finding leads for a 1000$ sale.
4) Very important: 3/4 of all buyers are not ready to buy, at that point in time. They could be having a bad day, low on cash, fight with their wife, trouble with their car ect ect. NEVER make just one offer. Do not spam them, do not bore them every week, but DO make another offer in 2-3 months time. Make a total of 3 offers to every lead.
