If all your client wants is a simple/stupid brochure site that they can maintain, just build it in Google Sites with a Google account they can own. You can do a whole site in 1-3 hours depending on how much custom graphics you have to build. You can reasonably charge $250-1000 depending on your time, and spend an hour training them on how to maintain it so you don't have to in perpetuity.
I've done this just a few times now (twice for free), and every time I'm glad I did. The more you dig into it, the more you realize it actually does allow for *some* customization. If you get into the scripting, you can do even more. I see tech-challenged people starting their small (1-20 people) brick & mortar businesses and being totally lost on things like document sharing, company email, web sites, cloud storage, etc. I just hook them up with the Google Business apps...$50/person/year. It's cheap and works.
