I used Open Source (WordPress) and spent nothing but some of my time.
Ron, It really depends on all of the requirements that you have for your website. It also depends on whether you outsource or build in the U.S. My company has a complex site with forms, user accounts, administrative back end and over 900 pages. It was built in Russia and cost in the neighborhood of $50k. The development took about 6 months. Hope this helps.
