I think you should simplify the service and make it strictly about fixing bugs in small programs. Why: because information is essentially perceived as worthless by the majority and almost any question a person could hope to ask is already one Google search or Stackoverflow question away from being answered. This pervasiveness of information contributes to the assumption that a person is entitled to it all for free (and that the person producing it ought to do it for free) - which is one of the main reasons businesses models built on content are so shitty.
"Please help me fix a very specific bug that's only in this one implementation in this current universe" is a lot easier to monetize than "please teach me how a for loop works." See what I mean?
