Wwhere can I find average cost for wills, trusts, medical directive, POAs in Florida

I would just call a few attorneys' offices and ask for an estimate.  I sometimes end up charging more than my estimate when clients change their mind or end up wanting more complex documents than they originally thought.  Be sure to look at the amount of time that your attorney took to draft your documents when asking for estimates.  Do you get the estimate in writing?  Is the attorney willing to work with you on a compromise?  I would encourage you to try to work with her or him once you get some information about what other attorneys in the area charge.
