Couch/Furniture Disposal

I am moving apartments in a few weeks and I guess I am looking for advice on a way to dispose of my large furniture that I cannot take to my new place (couch, dining table, etc - they are all wayyy too big for the small unit I am moving in to).

I am on my own so it's not an option for me to do this myself - plus being on the top level does not make it any easier.

Is anyone able to suggest a service for me that isn't going to break the bank or can offer me some advice? I am going to try and put the pieces that aren't buggered for free on gumtree in the meantime, but I would like to give myself some options if no one wants them.

Cheers ! :)
