Help me please. complex curved part

Hi there.

I am student learning solidworks...im starting to get quite good with it but am struggling to get to grips with complex curves and parts. I can make a nice cuved surface using the boundary tool but it will not let me use free form afterwards.

i have attached a few sketches of what i am trying to achieve.

any help with this would be greatly appreciated.

Thanks Will
