Where and how to advertise an artist's website?

[Mark]

My father has his website which features many of his oils, watercolors, prints and sculptures and I would like to know how to help him promote it.
He's not a social media guy being that he is in his 80's now. But, my idea was to advertise to his market of people who generally can afford a $1200 painting or $1700 bronze. He has some prints and giclee's as well. His specialty is sports but does other subjects.
Any help will be appreciated.
His name is jay o'meilia if you want to have a look first.
