Camera + lots of equipment - how much is it worth?

[Requiem]

Hi there,

I'm not entirely sure if this is posted in the correct forum, I chose this one as it says "have opinions from others about various equipment".

I have a camera plus lots of equipment that I am looking to sell, however, I don't know how much its worth and can't seem to find the information anywhere. I'd really appreciate some help. It's all in great condition. I have the following:
