recommendation for denver / aurora colorado lawn maintenence

[Dan McDougall]

Good day to you all. My tenant in a SFR in Aurora, Colorado is clueless on lawn maintenance (their responsibility per lease) and now even though the yard has a sprinkler system is scorched earth/weeds and I received a violation letter for City of Aurora. They have a relatively high water bill of $130/month that they have been paying so they seem to be paying for the water for sprinkler. Tenant is also not happy that they have to pay for water for the lawn but it looks like crap. It has been very hot and the lot is sloped toward the sun and no trees for shade so its always been difficult to make it look good. Any recommendations for a good Denver/Aurora area lawn maintenance company that can possibly bring the yard back from the dead without an expensive re-sod? Tips from others that have dealt with the same problem?

Thanks I appreciate it.
