It is a steep learning curve I agree, but companies who buy aircraft have to start somewhere so as to get going with that aircraft. Whether or not Pprune is the right place or not, the chap decided to ask for input from those who know and he will decide which road to go down based on that input. Don't knock someone trying to get advice.
I think for any company starting out new like this, a management company would be wise for say the first 12 months of operation so that the company can focus it's time and effort on it's own business rather than having to spend time also looking into all that comes with operating an aircraft.
If this chap plans to be based in the UK Midlands, I could point him in the direction of some very good management companies especially some who will not rip the @rse out of it.
