Is serious&#x2F;non-serious so binary?
My biggest issue is I wouldn&#x27;t want to commit anything, or give too much information away just to get a ballpark figure. I&#x27;d also assume that I&#x27;d be aiding price discrimination - There is no problem having up-front ballpark pricing <i>and</i> a &#x27;contact us&#x27; link.
Hell, just having a <i>high</i> ballpark figure will weed out students and small businesses.
