Drywall/sheetrock

[ricklev]

I dream tomorrow morning of getting into a cab on Lang Suan and going somewhere that sells sheetrock, having them cut two small pieces for me and paying them whatever amount of money they want for those two small pieces and then taking a cab back home to my apartment on Lang Suan. Can anyone tell me where I can have this done? Are there building supply superstores in Bangkok somewhere?

Thanks for your help!
