We needed a quick and easy cover for our yard after building our house. We purchased native mixed wildflower seed in bulk online; using a hand held small spreader it took maybe a half hour to cover the acre yard and the only maintenance is some watering.
It all depends on skills and physical ability. You can rent a rototiller and till the ground, rack out weeds and rocks, and then plant lawn or whatever you want in your landscape. You may want to do decking, fire pits, patios, etc. We had a lot of area that we didn't landscape after moving into a new house. A company came out and sprayed a paper mulch to hold the dirt in place until we were ready to do more landscaping in the spring. The stuff they sprayed was the same stuff they use when hydro-seeding a lawn, except no seed in the mix.
The stuff Ken mentions has a strong artificial look, but it’s green. I love a wildflower yard, but check your local ordinances to make sure you can have a natural lawn. You can also try green areas in your yard in all sorts of containers, especially those you can move around the yard. Then work on one lawn project at a time until you have your dream landscaping.

Plan out some flower beds with landscape fabric and mulch.
It is the fabric you put down to prevent weeds. Here's a link that shows it:
First decide what you want to do with the area. Loosen up the soil and then remove all weeds and stones. Rake even and top cover with a mix of bagged sheep or cow manure and top soil. Rake until even again and then top seed with a good quality seed good for your area. Sprinkle water over it each day to get it to germinate quickly. Keep moist until the grass thickens and covers.
