Hi Pete.
300 is a lot...true, just put that down in order of overshoot a bit costs and not fall short.
Realistically I might be doing plus minus 4 hs/week....so I will be rounding 200 year. That, at 80 Euros/hour rental price, gives you 16,000 euros/year...and flying whenever the plane is free.
Questions...questions...too many question my friend...
Please email me when you arrive in UAE or PM me and we get together and do some flying. My email is Brachetta (at) gmail.com
Cheers
Fabian
