I'm not going to call you selfish.
It's just not realistic
1. Pprune would struggle to raise the cash
2. It would also have to fund a selection procedure - also costly.
3. Who's willing to organise it 'gratis'
4. Pprune is good at offering advice, seminars etc. and should stick to that.
5. Pprune has a worldwide membership, is the sponsorship to be restricted to the UK.
and the list goes on.....
