We have a new PTO group that was using the school's account. The school no longer wants us to have the money in the school account. Thus, we're looking at becoming a non-profit. We have a person who does it but says it will cost about $1,000. I've read some posts that said it can be done for $400-500. How do I find a reliable, trustworthy place to do this and does anybody have any suggestions? We're in Wisconsin.
