My business is just blossoming, and internet presence will be important. Many of my customers will not be savvy at all, and won't be able to navigate complicated pages easily. Is a simple landing page with a general description of the company, and a list of services on the left hand side going to be too simple, or archaic looking? Is there a way I can make something like that that is also mobile friendly?

I would have every item listed on the left of the screen take you to another static page with a full overview of services, mostly text, but a couple as embedded videos. Below that will be testimonials, and contact information. I could probably build a contact box easily enough too.

I don't know ANYTHING about SEO, but I know that I offer a spectrum of services that nobody in my region does, so leads and stuff like that will certainly be necessary, I have no idea where to start there.

I'm a little out of my depth here, but my budget is low as I'm just establishing myself. How much would a service like this cost, simple website building and someone who can help me make google happy too?
