Hi dfw1942,
As I understand it, the "secret" to the sweet Vidalia onions is their low-sulfur soil. If you already have a lot of sulfur in your soil, you can't do much about that. I broadcasted some pelletized gypsum on my garden, so that eliminates any possibility of low-sulfur soil for me. Gypsum is calcium sulfate.
If you plan to start your onions indoors from seed, about now would be a good time to plant them. They come up looking a bit like little grass plants, and grow rather slowly at first.
If you plan to grow them from sets, there is a company you can order them from that will deliver them to you at the right time for your location. They have a wide selection of varieties to choose from.
I will probably just wait for the Vidalia onions to show up in the supermarkets.

By any chance, does "dfw" stand for Dallas Fort Worth?
