Try any place that sells mountain bikes or TA components. If you go to a good LBS they should be able to fix you up. Also here's a 61t from a UK source
Mdt do the Luna chainring in big sizes. You can get their number in cycling weekly. I think the address is www.mdt-products.co.uk. They do them as big as you need, I think up to 110 teeth.

I doubt you'll get anything cheaper as there isn't much call for rings that size. Why the need for such a big chainring? I think as stated earlier that TA used to do them, but it was for one of their spiderless crank sets.
