Many of the 206/207 operators require at least 1000 PIC and as little as 20 Hrs in type or sometimes time any 200 series, (For VFR 135 the FAA only requires 500 Hrs.) The reason these operators have these minimums and are fairly picky about who is flying them is primarily do to the nature of their operations. Many of these operations require the aircraft to be flown under demanding conditions which often requires the aircraft to be operated at or near its limits and with precision. So basically don't let the fact that it's a SE Cessna fool you. Many of the missions these aircraft fly on a daily basis would curl the hair of at least most city pilots...
