People have to start somewhere. This isn't rocket science.
I used to build my own sites using DreamWeaver and they worked just fine, it helped having a good graphic background and I kept it all simple. I use Photoshelter now as it works best for my online sales, they have a good set of templates and it's easy to set up.
The Op is an amateur, has no registered business, or cards or web name. Photographer or photography, as usual, will be added to their name and that will magically turn them into a professional, the web site will complete the illusion...and another one is born.
No it's not rocket science, it's another amateur that has been asked to to shoot for someone and the only way they can charge people is to create the illusion of being a professional. I guess you're right, it is a start. Step one, buy a camera, step two, make money, step three, start a business, step four, learn how to use the camera.
