I see you asked this question in March. How's it going?
In 1996 I published a family cookbook through Cookbook Publishers in Lenexa, Kansas.
http://www.cookbookpublishers.com/ That was one of the most fascinating things I have ever done -- I did make money from it, although that wasn't my goal. I collected recipes from family members and included family stories and pictures of family homes. My Mom was alive then and she illustrated it with original drawings. It was a lot of work but well worth it.
I must say, I think it's a great project for churches. I wish I could convince a group here to do it but they have their own fund raisers that they love to do and they're happy with the proceeds so I'm not going to push it.
I think there's a way Cookbook Publishers can set up your project online so you can have people contribute recipes to it directly, then you can go in and edit. They also suggest prices -- they have a price structure that you pay them for so many cookbooks and they suggest what you can charge. That way you can see how much profit potential there is.
