Sounds like you might want to look at the no dig methods. Charles Dowding is a good resource.
Take a year to look at how the sun hits the land and form a basic plan. Iteration is the key.
Start a compost pile, turn it often. This will be your soil.
Save your cardboard from deliveries, take off all tape and labels. This will be a compostable weed barrier.
Get some free wood chips from arborists. This will help retain water reducing the need to irrigate.
Lay down 2 layers of cardboard. Then spread out 6-8 inches of wood chips on top of that. Then spread your compost deep enough to sow your plants.
Coldframes, high tunnels, and aquaponics are all great tools to keep in mind.
