House Builder Required Nikom Kam Soi Or Mukdahan

My wife owns a property half way between Nikhom Kam Soi and Mukdahan. WE NEED TO HAVE SOME RENOVATIONS AND UPGRADING FOR AN EXISTING HOUSE AND WILL ADD ANOTHER DWELLING. NEED TO GET SOME THINGS ORGANISED BEFORE WE REVISIT ABOUT JUNE OR JULY. A CONTRACTOR WOULD NEED TO BE ABLE TO DO SOME WORK WITHOUT OUR PERSONAL SUPERVISION ALL THE TIME . ANY RECOMMENDATIONS WOULD BE APPRECIATED THANKS VINCE
