Jeff, what you said is fine and good, but it is also grossly underestimating how the web and search actually works. As it is, your site would be considered a "Hello, I'm Jeff" letter or brochure site. I say this because it will likely not be found via organic search and will require people to directly type in your site based on previous knowledge of it's existence. Beyond an area code, I don't even see where you might service.
A better discussion or thought point might revolve around when you said "it will serve it's purpose for now". What does that actually mean to you and what are your expectations for your site?
