Well so far it's looking like it depends where you live. Also your equipment size as stated earlier. I tried getting a 2 acre place around here and offered to do it for $85. I guess that was too much. I didn't get it. There wasn't much trimming or blowing.
As for your partner being your wife I think that's cool. My help is my wife as well. All the money then comes into the same household. We have been together for about twenty three years now so getting along with each other is hit and miss. I'll tell you what though, it's hard watching her walk with a 21inch while I'm sitting and mowing. That's why I stay in the back behind the houses. I can't see her from there. LOL!!!
