Finding someone "experienced with specific tool set" is also not a trivial problem.

It is even harder if you don't even know how to verify that person really is experienced with specific tool set.

So it goes like "pick your poison", hire generic dev and account for learning curve or spend money on recruiting fees/time for finding an expert. Where I would not be so quick to say "expert shouldn't cost too much" - because I can imagine expert taking less time but costing orders of magnitude more than generic dev.
