My Fooles Troupe & personal sites were written to be easy for the blind from the beginning starting in 1996. I even got an award for it.

There were heaps of reference sites around telling what you need to do. Doubtless a search will find some of them today.

Clever 'Visual only' graphics heavy interfaces are right out! :-)

Quite easy if you follow a few basic principles as you write the site. May be a bit frustrating if you have to rewrite it all.
