What's the best way to level out an uneven yard?

Your options (as I see it) in order of more expensive.

Option 1:

Well personally I would do it myself but I really don't know how large of a yard you are describing. I would suggest a Tiller and some elbow grease. Call your hardware store, they can probably tell you where you can rent one or maybe you can borrow one from a friend with a garden.

Option 2:

Don't underestimate the power of beer. Invite your friends over to help. I find most of my friends can be bribed quite cheaply with food and beer but your mileage may vary.

Option 3:

CASH! There are alot of out of work people these days and many are willing to work for cash. Take a picture of your lawn and be prepared to explain exactly what you want and what you are willing to pay to get it done. Now put it on craigs list, approach people at the unemployment office, put up flyers. Whatever it takes to get the word out. Someone will probably take you up on it.

Option 4:

Hire a landscaping company. This is probably the most expensive but unlike the other options it's also the safest. No arguments with your friends, no shady characters around your house and best of all, no sweat off of your brow. Plus any decent company will be insured against any damage that may occur. If they screw up, it's their *** not yours.

Good luck

Add grime to the low areas. The grass will have to develop via the new dust. This may increasingly do most of the work. Once the dirt has had a threat to settle a bit, that you could get a curler, that get's stuffed with water, and roll out your yard. All a curler is, is a large wheel that has tons of water in it for weight. That you could frequently rent one from a instrument condominium company.

call around a sell the dirt to either landscapers or construction
