Thailand is definitely doable for 1000 dollars per month.
Rent 1 room apartment = 150 dollars per month
Food = 300 dollars per month (Eating in Thai restaurants the non-expensive options three times a day. With cooking yourself it could be done with 100 dollars anf healthy)
Leaves still room for 450 dollars for visa, health insurance (if even needed), scooter rental, power etc
