Buying grass seed on line in Thailand

I have just put some really good soil around my house and it is only about 20 square meters of earth. I can see that there are a lot of different grass seeds for sale on Lazada and I was hoping that someone out there has had good luck with one of them. If not, I will buy sod. But here in Chiang Khan I do not see where to buy any any. Does anyone know where we can buy good quality sod that will survive the hot dry summers we have here. Water is not a problem with our 42 meter deep well and we have 3 ponds also on our 6 rai rice farm.
