Hi, and welcome!
It sounds like you have a good source for business with your husband being a realtor. During this tough economic era, it's a good business to get into.
The forums are chock full of info so grab a comfy chair and some coffee and read, read, read! Take notes. Start organizing your info and research. Then when you find you have questions...ask!
I know there's a lot of folks here that are willing and eager to help. I may not have done foreclosure cleanings (well, I did a few...but my focus was on resi clients) but I can sure help with some of the basics of running a cleaning biz. If I don't have the answer, I'll try to help find the sources to get it.
Cleaning for Heroes
The only 501c3 nonprofit in the cleaning industry that improves the lives of heroes, one household at a time!
