The Time Traveller's Recruitment

Recruiting for a Time-Travel Agency should be easy. It isn't.
With the rising cost of History Degrees and most potential candidates having too many other commitments, and the rest of the pool thinking Netflix is the height of historical accuracy, finding recruits that don't require months of re-training is becoming... difficult.
Recruiting Field Agents is simple. Just find the nearest person who has theories about how to change history, and aim them at prospective time travellers who have a different plan. All you have to do is keep track of where and when the Agents should NOT be sent.
Recruiting the more specialised support staff? ... well, that's a bit more difficult, and it's not getting easier by having Management poaching the cream of the crop in an attempt to get some more competent Field Agents.
