Start / End Dates in conjunction with man days

[loobs40]

Hi all,



I am creating a plan for a client where I have some tasks they need to do.

A task may only actually take them 0.5 day, but I don't mind when they do it as long as its done by a certain date.

So I want to show on the plan for their guidance, for example

start date- 01/10/13 (can start the task on or after this date)
end date = 14/10/13 (task must be completed by this date)
man days = 0.5 day (i.e. how long the task will actually take)

Is this possible in MS Project Professional 2010

thanks
