Old stone paving stone advice wanted please

[Alcoblog]

Hello .... just wondering I someone can point me in the right direction to about four square metres of old paving stones to make a gardening feature. I don't mind if they're broken. I don't want to spend a fortune on them as I rent my house and would be unable to reclaim any money on them. Oops .... I've just posted a serious question unlike my normal drivel! If someone suggests I should dig up a few of the really nice ones outside City hall you're being daft ... to heavy to get back on the bus!
