Where can I sell an established Acer

We have an Acer in our garden which is around 3 metres by 2 metres in size. We're sadly going to have to lose it as we want to build an extension over where it's currently planted. The last thing we want to do is just chop it down and take it to the tip but we have no idea who to get in touch with to come take it away.
Ideally we'd like to sell it and have been told it's worth £1000 (though my research tells me that's probably old information and the current going price for an Acer like ours is probably a lot less). It'd be ace to get something for it though - even if we only get a small amount it'd fund a new Acer which is definitely what we'd want to do - we live in Bristol, on the doorstep of Westonbirt, and I think it's illegal for a garden in these parts not to have an Acer.
So, has anyone any idea who we could go to to talk about this or is the reason my online research has been fruitless because there's no market for established Acers?

ebay? gumtree? freecycle if all else fails
Maybe contact whichever local college runs horticultural courses and offer it to them for free if they can come and get it? They might just have somewhere for it and it would be a learning experience for students.

I think Guy is tempted by the fact if could be worth £1000.00!
something is worth what someone else is prepared to pay for it
The trouble with moving large trees is that if you dont get all the rootball, its likely to die. We tried to move a 5 ft tall acer from his mums, it looked ill for six months then died.
It might be worth something if he has it professionally lifted and containerised and pays for transporting it.
In the ground it's going to cost someone a lot of money to move and is worth very little as it is.

Ebay, buyer removes. You'll soon find out how much it's worth.
Brilliant - thanks folks, great advice as usual!
I'm not overly bothered about making a profit from it - just curious if there were a market for such things really and if there were great - I'm sure I'd have ploughed any money from it straight back into the garden anyway knowing me!
End of the day I'd much rather have someone just come and take it away for free rather than have it killed, so I think I'll go down that route - I've got plenty of suggestions to work with now and I love the idea it might end up somewhere i can keep checking on it! I use Streetbank and Streetlife a fair bit - they're both like freecycle but only people in the surrounding 2 - 3 miles can see what's being advertised - so I might give that a go - it's a long shot but you never know!

I hope it finds a nice new home
