It sounds like you have a decent blueprint for an initial discussion with an estate planning attorney. One question I would have is whether or not your father is trying to avoid probate. If so, then a Will is probably not the best choice, since a Will is only effective once it is admitted to probate. If you structure the assets so that title passes automatically upon death, then probate would not be necessary, and neither would a Will.
You are talking about perhaps 2-3 hours worth of work. I would expect the fee to be in the area of $400-500.
