I am a lawyer (although I don't do estate work). It really depends on what you need/want. You should have a will, power of attorneys, durable health care POA, etc. You might as well do it all at once. I would highly recommend going to a reputable attorney rather than doing it yourself. Every state has different laws as to the number of witnesses, etc. If you don't follow the rules, it may not be a valid will. Get some recommendations from friends and family. Every situation is a bit different so it is difficult to estimate but between $600-$1200 seems reasonable to me.
