Fedora21 on a macbook pro - willing to pay!!!

[CS DBA]

All;

I want to run Fedora21 on a mid-2014 Macbook pro 13" retina...

I can get the install done easy enough but I want all the buttons & such 
to work such as :
- auto setting for the backlit keyboard
- the mac keyboard keys for screen brightness
- the mac 'show desktop' (F3) key
- sound volume keys
- etc


Can anyone point me in the right direction? If some of these just don't 
exist I'd be willing to pay for it's development.


Thanks in advance...
