Sram 1x11 bits

Hello, I'm after some sram stuff, hopefully either rival or apex x1.
I'm after a rear derailleur, crankset, shifters, cassette and chain.

Any help much appreciated, mostly by my wallet as it'll stop me buying new!
Cheers

I've got a BB30 Rival 1 Crankset, 42t used for 150 miles.

I'll be willing to let it go for a great price if it suits your needs.

Now discovered I need a GXP bottom bracket.

Oh and a left hand rival brake lever would be good as I'm going 1x11. Any one got one?

I've got Rival and Apex 10 speed RD in black.

I'd buy a new BB though.

Yeah that comment isn't clear, I meant the crankset needs to be GXP. My bad!
Also, looking for 11 speed. Thanks for the offer though.
