I don't normally advise other websites but this one is so niche that it really suits the problem you describe. Home | Stepping Out of Squalor

I am a hoarder and also live in squalor. I tried getting help from TLC's Hoarding show but the so called 'organizer' that was assigned to me was horrid. She moved things into bags and boxes and stashed them in the garage/closets/my office but there was no actual organizing that happened. She was good at cleaning the dirty floors and mess but she didn't have a clue how to organize. She has her own company but she mostly does estate sales and I was her first 'real' organizing challenge, I think. Two years after the show was complete we finally moved some of the stashed boxes in the dining room and we found my son's guitar in the dining room closet that he used to play Guitar Hero. Seriously? Who would think to put a video game guitar in the dining room? That makes no sense!

I do find the site I gave you helpful at times. There are different ways to use the site, by posting daily lists and such but most helpful for me is their chat. It is not a social chat although sometimes we do talk about some social things but mostly people go on challenges on the top of the hour and bottom of the hour. You choose your goal whether to pick up ten items or fill two garbage bags or whatever you like. And it is okay to be in chat and not even do all the challenges; you can be a cheerleader and give everyone who is doing challenges hurrahs when they return.

Also there is another thread somewhere on PsychCentral where people are working on clutter but right at the moment I cannot recall which section it is in. I am sure someone else can link us to it later.
