Those numbers are great. What happens when your 6 wheeler, loader, skid steer, one tons, plows, sanders break down? Because they do. Or one guy calls in sick so you have a machine/truck with no driver. I've had seasons where I've grossed almost 30k and netted a whopping 2k due to breakdowns and fuel rising. To be honest I've made the joke that during that season I would have made more money as a cart jockey at Wal Mart and I wouldn't have been turning wrenches at 2 AM in -30 weather. If you make money great, I do as well, but if there were other alteratives I would be more than willing to explore them.
