LF: Mirror-top for table

[robbiex1]

I'm looking to replace the top of a glass coffee table with mirror instead. It's roughly 4 ft. x 1.5 ft. in size. Doesn't have to be too strong as it's just a coffee table supported at each corner. Any idea where I can find a custom-
sized mirror that is strong enough to be a table-top?

Thanks in advance!
