You best bet (in my opinion) is to find samples from others who have already achieved their 501(c)(3) and adapt a set of those proven bylaws.
One critical thing they look for is a "dissolution clause". The IRS provides boilerplate language and you really don't want to vary much.
Another issue my be your "Conflict of Interest Policy". This is probably a separate document - not actually part of the bylaws. But then your bylaws would likely have a generic statement about following the policy or adhering to policies adopted by the group.
Perform a search in the Forum with those two phrases and you'll find some older postings on these topics.
We have discovered that we only have "proposed" bylaws and I am trying to revise them to meet the needs of the IRS. We have already been established as a 501 3-c many yrs ago. I went to the IRS site but was unable to find the required wording. Thank you!!
