As an example of the markets you are talking about, imagine 3 people aged 25-35, starting a new business. I am that market, and I have made at least a dozen purchases. Each time it was like this:

  * hit some roadblock on the way to accomplish X
  * find 3-6 solutions, pick the one most valued/recommended/easiest/etc
  * slap down the debit card
  * never think about that roadblock again

My lower bound is probably 5:1. If you can save me five hours of work per year for the price of one hour's income, I'll take it. A good example is DNS hosting, or a SkypeIn number.

If everyone's out digging for gold, start selling shovels.
