I recently wrote a page on my website
for clients to read after having shown up one too many times to a person's house who had previously expressed concern for the time / cost they feared the move would take - and yet were totally unprepared when I got there.
My girlfriend suggested that this information would help many people, even those who don't hire me (I assume it is because you don't live in the area, so I forgive you).
In my 5 1/2 years of experience, I have found that a small, one-person, studio apartment move can take anywhere from 30 minutes all the way to 4 hours, all with the same amount of total stuff.
It all comes down to preparation.
