Starting a 135 op?

All,

Can anyone tell me in this day and age if it's practical to run a 135,
IFR one-man, one-plane operation and make at least some money,
considering insurance and FAA related red-tape that would accompany
such an endeavor? If so, how many hours would one require (from a
realistic perspective) beyond the 1200 required to act as PIC in a 135
operation?

Would adding a second pilot increase the red tape exponentially?

I assume there must be plenty of bush pilots flying float planes in
Alaska doing just this same thing, right?
