Where To Sell My Wood / Logs

We have planted some (5000+) Acacia Mangium, Krathin Thepha in Thai, and next year we have planned the first thinning.

Does anyone have some information where to sell the wood of the first thinning, guess will be paper-industry, in preferably the Isarn (Chumphae - Si Chomphu area)?

Also for further down the line any info where I can sell the mature logs will be greatly appreciated.

Found some websites but looks like mainly south Malaysia orientated.

Noticed that more (local) people in the area are struggling to find a market for logs, I am sure there is a market for lumber but just need to find the right contacts.

Any help is greatly appreciated.
