I do not know the current rates, nor how it is calculated, or
determined, of any of those firms, or individuals.
In years past, the most common models for charging clients were:
* Flat rate;
* Specific currency amount per unit of time;
* Per incident;
with different rates being charged, depending upon which tier the
requested service fell into.
