Any building supplies (Bandera, Texas or nearby)

My little sister having lost her husband last October, started her own homestead.
She did have a home of her own but squatters took it over and destroyed it.
She's now trying to rebuild it.
I'm trying to help her acquire either the funds or the resources in order to get this accomplished.
If you know of any resources available please let me know.
Thank you ever so much.
