75 bare root trees...now what?!

I came across 75 bare root saplings at a yard sale today. 25 Redbud, 25 Dogwood and 25 Gray Dogwood. A guy had bought them from the state nursery and for some reason didnt want them so I gave him $10 for them. I really dont know what to do with them, I just couldnt pass them up and let them die! I have a big yard so I have room for a few of these to go in permanent homes.

I would like to try my hand at being a nurseryman and grow these up for a year or 2 (or more). Maybe use them for gifts or sell them at a later date. Question is-how can I plant them now so that they are easy to move in the future? I was thinking of building a berm out of compost and mulch them-would that work? Any ideas or direction is appreciated!

Look in to "heeling-in" fruit trees. I was in a similar situation a few years ago with a load of free trees and I heeled them in (basically planting them at a 45 degree angle in a garden bed) for a year or 2. The fruit trees were easy to dig out have done well but the nut trees with tap roots did not fare well. Good luck!
