Maybe it's because I'm slightly younger, but I'm coming at this from a different perspective. Maybe I'll come to learn that I was naive to begin with, but at this point I believe I have a great, perhaps new, way of running a web design, if you can even call it that, business.
I'm aiming for the small businesses, the ones who are just glad to be online as it is. I might only know a few small businesses, but every single one of them had almost zero involvement in the actual designing of the site. They just want a professional website to reflect well on them in front of the millions of people online.
What people should realise it that these small business (salons, restaurants, florists, bakeries) will probably have, and want, 10-15 pages like they have on their current site. They'll probably want the same information or a slightly altered and improved version of the content already on their site. This, despite what another user suggested, won't, in my mind, become an endless wait for them to send me the info they want on their site. Firstly, I'll just copy and paste their current content if they don't want changes and if they do, while waiting for them to reply to my email, I'll have their old content included so they can see how it looks and that'll excite them enough to get it sent quicker.
My business would be an express service because, from the little knowledge I have, small businesses don't want to wait a long time for their site, quite the opposite. Sure, there will be customers who take their time, but I think the reason this user suggested people take a long time to reply is that you're taking a certain time to make a site and in the meantime they may have become less excited about the project and it's not immediately on their mind. My turnover time will be so quick, they won't have time for the excitement to wear off.
Maybe it's not the best way to go about treating customers well, but I'd see it as a production line. I'd have emails which need to be sent to them sitting on my computer as drafts. When I get a contact form from a customer from my website, I copy and paste the email I've previously written out and send it to them with 5-15 theme options. They tell me the one they want and let me know if I'm using their current pages/content or whether they want to make changes, and then I'll have the site done in 2-4 hours. I'll email them another draft email but change the URL to their site URL. Then I'll send them a draft email of wordpress instructions and we're done, onto the next one. They may not say it was overly attentive customer service, but they won't be disappointed with it either, because they'll have a fantastic new website, a maximum of 36 hours after contacting and for only £150.
The bottom line is that I feel I'm new to all this and can see it from another perspective and, with respect, some of the users who've replied are stuck in their old ways and can't or won't see that their are other opportunities and more profitable ones too.
