Have you thought about what products you'd like to sell? I mean maybe you sell the apples themselves, or maybe you just grow cider apples and make cider. Maybe you do as others suggested and have a "pick your own" orchard so that you cut down on labor (at least the picking portion). I know I might catch some for this, but have you thought about growing organically? It seems to be a growing market, and if there is nobody around with that niche exploited, you might have found yourself a foot in the door and something that'll make your place stick out. With DR varieties, you might be able to get that done with 3 growing helpers. Also it'd give a huge lesson on how nutrients are recycled in the environment. I'm no apple grower, so I'm sure that it's harder than it really is. If you don't want to, no worries, but I'd say look into it and make sure before you spray anything because it's something like 5-10 years without anything on your ground in order to be considered organic. Again, I've got no experience with growing any apples on a large scale, and I'm not too picky about my apples, as I eat the ones with spots and have ran into worms a few times.
As far as the business goes, I'd say focus on something that'll make you different. Whether it's the products you offer, or a pick your own type deal. The big thing is that if you have a few orchards nearby, you might just be another fish in the pond. You need some shiny scales or something to make the people driving by notice you. Why should they go to you and not the other guys? How are you and/or your products different? If you're fine with it not working and you end up with your own orchard for you and your family and friends, I'd say go for it (funds permitting)! If you're trying to make this a big time business venture, I'd say give it a ton of thought, and then think some more. Definitely feel out the market with your local fruit and nut growers associations. I've had a great deal of help from mine, and even got invited to a conference this summer. Most of them will be well enough established that a small operation or start up might not be a threat to them, especially if you approach it from a part time, family type deal. Again, I have no idea, about the business aspect with any specificity to apple or any fruit growing.
Definitely lots to think about, but also lots of fun!
