Depends on the size of the project. Three years ago I bought a foreclosed home, totally overgrown, empty for four years. I paid a five-man crew $900 and they spent four hours unleashing hell. 20 man hours. Chipper, etc. No way in hell I could have tackled it. I put on a pair of ear protectors and watched. The entertainment value alone was worth $100. I had other estimates as high as $3,000.
