Planting fruit trees in the summer?? I need some advice.

Hi to all! I have started a food security business in Mauston WI and I am putting together some "Packages" for people to choose from.
The part I am unsure about is obviously I can't schedule all installs to be in the spring or the fall. With that in mind, what kind of stories/experiences have you all had installing/planting fruit trees in the summer? I want to put together some packages at specific price points so many people can afford to have edible perennials in their landscape. An example would be a $500 package that includes one fruit tree, two companion shrubs and so on. The customer gets to pick from pre-made lists as to the type and cultivars. Then I come in and install the planting. I would have a couple $ packages available. With that in mind, have any of you had any experiences directly related to what I am planning to offer.
I already offer consulting and design. I know that many people would entertain the idea if there was a solid number/cost associated with the project.
Thank you all for any thoughts or advice you may be able to offer.

Summertime is difficult, as trees have leaves which are respirating and losing moisture and dry out quickly.  The humidity is usually lower and even if you shade them until  they are established, it is just not the best timing.   Maybe you could experiment with a few to see how well they do.  As you already know, I‘m sure, you have to make sure the plants are  turgid (well hydrated) before taking out of their original pot or bag or digging them up to transplant.

For me it's 100% failure. For more gentle climates it's possible that it could work to some extent.
