Tree surgeon?

[MrChips]

Anyone recommend one near Reading or that covers Berkshire? We have 2 trees that we'd like cutting down, maybe including grinding/removing the stumps. They're about 15-18feet tall, and quite thin (i.e. base of trunks are max 1ft across).
Just looking for someone who knows what they're doing with a chainsaw, and will take away all waste.
Anyone know anyone?
