I don't know what you plan but ideally, to have an "orchard gameplay" it would be with something like the "umbrella" collectors. Weird for apples but credible for plums and cherries.
About price, make a test on the 1Ha field at the starting US farm to see how many trees you can plant, it will give you the base for max liters/ha and then what you can expect in a season if it's a 1 yield/year. There you'll be able to evaluate a possible €/liter price.
I understand I'll not touch to the present juice factory if fruits prices may change ;)
