Hi J.,
I used cloth diapers until my son was 8 months old (he is now 2.) I loved them!!! I used a diaper service, where they provided the diapers, wraps, and an odor-proof diaper pail, and they picked them up once a week. It cost $45 a month, with a $100 startup fee. I changed his diaper about once every two hours (or as needed.) At night, I double-diapered him and used a larger wrap to prevent leaks and avoid night-time changings. (I don't believe in waking sleeping babies!)
After we found out we were moving to an area that did not offer diaper service, I canceled the service and washed his diapers at home during our two-month transition period. I had inherited about two dozen cloth diapers and some wraps from a friend, so I tried my hand at washing them at home. This was DEFINITELY a money saver, but more time intensive!
We've been using disposables for the past year and a half, and I have to say, we really didn't save money going with cloth. If you are trying to save money, don't go with a service. It's convenient but comparable to the cost of disposables. The best case scenario is to buy wraps at second-hand stores or inherit a cloth starter kit from a friend. But get ready to spend more time and energy in your laundry room that ever before! =)
If you do a search on "cloth diapers - Portland, OR" you'll find a number of websites where you can order cloth starter kits, get instructions on how to wash diapers at home, and get numbers for diaper services in your area. As for me, I loved using cloth diapers for the first 8 months, but they were so bulky he was having a hard time sitting up. As soon as we switched to disposables, he starting sitting, then crawling shortly thereafter! Honestly, for my next child (big fat IF!) I would probably just go with disposables from the get-go, landfills and all.
Hope that helps! =)
