Here are my humble offerings to aid in your quest.
First advice is scale back your program and decide what you want to accomplish and in what order. Set a timetable once you figure out your budget and then you can plan accordingly. That works best, in my experience, no matter how much or how little space you are working with. I've seen many a piece of land with too many unfinished projects...including my own. There is no better teacher than experience!
Tony M has done a beautiful job with his place, so hopefully he'll see your post and give you some input. I'd take his advice anytime.
Things to think about are:
1)Testing your Soil - This is important so you know where you're starting.
2)Sun Exposure - Watch what gets how much sun and when, and remember that it changes from winter to summer. Trees, no matter what kind, count. Remarkable how we forget this simple thing.
3)Water Sources & Irrigation - Existing and what you're willing to add. This will have a lot of bearing on what plants & program you eventually end up with.
4)Equipment - If you have that much acreage you'll need good equipment and most importantly, the right equipment. A simple tractor will do for starters, but what attachments...ah, that is the question!
5)Restrictions & Regulations - Amazing how these pop up AFTER you've made plans...and sometimes after you've spent LOTS of money.
Another source would be Holistic Resource Management. They have a website and they're not afraid to use it. Walt Davis works with them from time to time and is wonderful at this. He's excellent at helping people restore land to good pasture, and I wish he'd slow down long enough to write a book! (He keeps promising...) Let me know if you'd like to get in touch with him. He's available for consultation at a reasonable fee and will drive down from southern Oklahoma to your area. If you send me a private mail I'll happily put you in contact. He's the fellow who advised Marie Tedei on her pond problem, and that's just for starters.
There are others of us who can help with vegetable garden plans and perennial beds, Xeriscaping, etc. It all depends on what you want, and sometimes it isn't what you thought when you first moved in.
Good luck! It's gonna be fun!
