I can't help you much because I just acquired my first Midget White. He's a cutie and is probably going to end up as a pet and not on the table.
The only way I can get Midget Whites is to purchase hatching eggs. Shipped eggs are a gamble and I only got one to hatch. They are such small poults that I suspect that it would be extremely high risk to ship them.
You might try putting a wanted ad in the classified section here on BYC. Also try some wanted ads on Craigslist. Figure out how far you are willing to drive for poults or adult birds and use Craigslist in those areas, too.
There are lots of people raising turkeys in Texas, where you are, and maybe you can locate someone who raises Midget Whites.
