open source web design

http://www.oswd.org/
Recently we registered a domain and posted 'under construction' page. Shopped around for some one who can quickly create few web pages to spread the word. I got quote from 2 sources and they were much more than $250 with couple of hours investment from me. I have basic understanding of HTML and I was wondering why we got to invest more that kind of money for the web design that is a living document - meaning will change multiple times in a year.

On a weekend we typed "web design open source" on a search engine. Clicked the first result. Picked up a design and we were able to quickly make a imageless set of web pages. All in less than 3 ours of my time. Now, I wonder if my >$250 would have to me better web site. Images take long time to load any way and I got many folks who would load the web page from lower bandwidth locations.

Wondering if open source has taken away $250 of my business from some company/individual. What would happen if this proliferation grows where every thing is open source - no one nothing gets paid. How would any one make money - would we get back to community funding as it used to happen many thousands of years.
