OK, it is an old post, but that idea never really got addressed.
There was a service that I used which was really good called Expert WordPress and it did pretty much what he is asking, but Alex Sysoef closed it down last year, so there is nothing now, but it was really good.
The point is, that a lot of people find ANYTHING to do with databases, code, etc to be totally overwhelming. The point is not whether they should, or not, but whether someone can address that need as Alex did - quite successfully.
Fantastico is easy, but uses all the defaults, so it makes things easier for hackers. A program is crystallized expertise, so an opportunity exists there. Total newbie runs it, gets asked simple questions and the tough choices are done, but in a professional way.
