Forget about healing your wife's mind as there is a high chance of failing in this. 

Sorry to say, with 11Mio. Bath on hand, you only can build a very small fraction of this dream castle... ....stop dreaming...

A great place to live there. The beach, the breeze with a small strip of forest - and a visible sunset - not to forget this.

Holiday Inn Phuket is a great place to stay. Friendly staff, big swimming pool, good food,  great central location. 

Be aware that in Phuket, nearly everything is closed, even 7 Eleven. If you select a beautiful remote place, you will then feel like lost in the nowhere. 

If you like busy non touristic  normal Thai life, then stay in Phuket Town.
