Does anyone know the approximate price of timber (per cubic metre) in Thailand?

I've just had a dead tree cut down and I want to get some idea of its value. I think it's either peltophorum dasyrachis (Thais call it araang) or peltophorum pterocarpum (non-sii). The chain-saw guys have cut it into slabs about 2200 x 100 x 25 but there's plenty more to do at the moment.

Any info appreciated.
