If you google Scoop on + the name of the nursery, it will show reviews from a garden watch dog, Dave’s Garden i. e. Scoop on Fastgrowing ptree nursery.

Fastgrowingbtree nursery has more negatives than positive reviews.
Plant me green is a mixed bag. If I were you, I would not buy from them. You may even get mislabeled trees.

Here is the Reference category of the forum for reputable nurseries.
Nurseries list.

People here often buy bare root trees. It is a lot cheaper and can be easily established. Potted trees are expensive and often are root bound.

Honestly, this time of the year is rather late to buy trees. Check those reputable nurseries. Hopefully, some of them may still have the varieties you look for.
