The ninth operator that you talk about was probably Fridge Air as mentioned in the "Essential Guide". Unfortunately, they have closed their operation in Maun. Also, as Hatton pointed out, they were a refrigeration and air conditioning company (but that didn't stop many people from sending hopeful pilots in that direction).
Other operators that could be included to make up to 9 would be Flying Mission Services or Helicopter Horizons. I didn't mention either of them because FMS pulled out of Maun awhile ago, and HH have their wings in the wrong place.
As for work, don't count on getting a reply to your emails. We almost exclusively only consider the applications that are made in person.
