Project Hospital

Prestige and money is easy to get through accidents. If you want to ensure easy accidents close the orthopedy and general surgery departments and buy a lot of staff for remaining areas. When you've gotten the prestige and money objectives you can quickly open all the other departments. If you're tight on cash take out loans or sell unnecessary items such as the ambulances. You won't need to pay it back since the achievement pops as soon as the last department is operational.
