Have just read through the plan.
Whilst I admire their spirit, this is extremely unlikely to work and I think it is verging on comedy to expect such profits from the operation.
If you are to make J32s work, you need very high intensity if operations - ideally eight or ten short sectors a day - and with only two aircraft, they will have insufficient critical mass to justify the sales & marketing spend to promote the operation. I just don't see it.
