Trek Steel District comes with a front basket, and REI has the Barrow which comes with a frame mounted front basket. They're both still 700s though so it's debatable.
Soma looks like they have a few great options that look quite good, without being several thousand dollars like the Taiwanese bikes imported from Europe. They make the Pick Up Artist complete bike, which is a 20" front wheel linkage steered bike, the Tradesman frame which is a direct steered 26/20, and they import one called the Yasujiro Mini Cargo Bike which has 20" wheels. Worksman also might be worth looking into that have 26/20 wheels too.
non specialist, Soma and Velo Orange have some 650b models to look into
