This is actually a sad state of affairs. It used to be that the salesperson was exactly the kind of guy who could solve this. Now they're just too busy padding deals with stuff almost everyone knows you don't need.
It's a top-down problem. If the company's executives are pushing salespeople to work in the 1990's-era enterprise sales model, you get websites with zero useful information and a phone number for upselling.
That's kind of what I was trying to say. The fact that "sales" is so bent on selling you stuff instead of getting you the right stuff for what you're trying to do instead is a problem.
