We had the same problem when we started on our field. Got a man with a bulldozer to smooth the surface and scoop out a natural pond for drainage as it was boggy cow pasture before. Then put up a fence and planted shrubs to make a windbreak and attract birds. Put the rest to grass except for a terrace seating area at the back of the house.
Over the years we've dug out beds and planted more stuff and bulldozer man came back to build a railway sleeper retaining wall and scoop earth about to make a flat fruit and veg area behind the house.
You need to decide what you want - seating area, pond, woodland area, shrubbery, island beds, evergreens, fruits, veggies, pergolas, arbour etc, children's play space, doggy space, greenhouse, shed etc. Work out how much time you want to spend outside enjoying the space and how much time you have to spare to maintain it all. Will you buy in or grow from seeds and cuttings? Does it have to be instant or can it develop as you and your ideas develop?
Try and draw it out on paper then start in one corner and work out, or back, or along as time and budget and plants allow..
