Needed: Thai Accountant For Tax Return

I need a Thai accountant to prepare my Thai tax return. Any recommendations of an good accountant? I assume it’s a pretty simple process but just want it done right and on time. I'm US and will have my CPA in the US do that return. But he will need my return here first.

And what by the way is the deadline to file?

Any tips on filing, saving money, etc.?

Thanks
