Economic impact : You will be increasing your weekly expenditure with a new staff member. I suspect a lot of managers will want to run a level 5 Coach minimum, so look at an additional 20k+ in staff wages every week.

I think there are several ways to avoid immediate economic impact.
We can also consider the possibility to give more knowledge to trainer. Then we will not have additional 20K+ salary
