Too much camera? Stepping down. Omd Em5 selling it

So last Sunday went to San Diego safari park, nice place for picture taking. I'm no pro but just want the best gear available that I can afford. Well I guess I got frustrated. I was changing lens often from the 45 mm,rokinon 8mm FE lens,the 12mm 50mm and zoom lens. Just too much. Then trying to figure out the aperture etc....

I guess i got overwhelmed . I didn't want to just leave it on Auto.   Maybe I need to learn more or step down to a Sony  RX100. I  feel like selling my system. Too much camera for me.

My question is where can I sell it besides EBay. Where can I get top dollar? i have the body with kit lens, oly grip ,45 mm, 8 fish fish eye,40 mm- 150 mm. All in like new condition ( 3 months old). I had a bunch of gift cards on amazon so I only came up with $200 to cover whole system.
