Any landscapers or suggestions of one?

[colorider]

Have a large yard that I turned into an remote control car/truck and 50cc motorcycle race track. Now I need the yard landscapes as that did not turn out to be such an easy thing to maintain and it's time I have a yard that can be used for something besides a race track. Also, the wife is ready for it to be a yard. Need a large section leveled and sodded. 2 tiers of rock or wood retaining wall put in. Sprinkler lines and heads put in. Already have the control box and lines going to the valves. From valves to heads and heads were casualties of the race track.
Anybody do this kind of work or have any suggestions. Told my wife while I was building the track that just because it's a dumb idea doesn't mean it won't be fun. Well, it was fun for a few years and now........ well she is not happy with my decision.
Thanks in advance. Wife will be REALLY happy I'm working on this.
