Where to get a glass/ perspex corner shelf made?

[ampere]

We have need of the above on which to place an -ahem- Buddha! It's not that heavy so I'm thinking tough glass or perspex as a corner shelf, a 1/4 circle of minimum 350mm radius, anchored to the walls in the corner.

Where can I get such a thing made? What do you look up and where? We're in Southampton. I have seen the odd 'corner unit' but they tend to not quite be the right dimensions or have clunky, tubular metal support legs. With special dust trap shelving beneath.

Any thoughts welcome.

take the measurements in to a double glazing provider who does glass cutting on site. I had 2 table tops of 15" radius with a bevelled edge made in a day. if you take your measurements in they can do it.with it being a shelf it will have to be toughened glass or plate glass
