Basement Clean out

We moved BACK into our house after having it rented to others for 5 years. I need help unpacking, organizing and getting rid of unwanted stuff. Renters used the basement as a dumping ground for boxes and other things they weren't sure about. I would like to tackle this job on Monday, May 30th--the holiday! I think I will need about 5 hours of help. It is a basement, but it's not too musty. We are in Cambridge on Rindge Avenue, equidistant from Porter and Davis Sqs.
