Learning English In Sawan Daeng Din

Hi all, my gf's sister would like to learn some pretty basic English. She is based near Sawan Daeng Din in Sakhon Nakhon, so if anyone knows anywhere it's possible to have lessons around there please let me know! It may be possible for her to travel to Udon too., but Sawan would be better. The cheaper the better too!

Thanks in advance.
