One organization that I have used regularly is www.narpm.orgJust find the PM, introduce yourself, let them know what you are doing/looking for and ask them if they can provide contact info for agents that either own REI property or work with REI consistently.

Organizing an LLC should be fairly easy and cost effective.

Anyone have any experience with or thoughts on assigning a contract to a local Housing Authority or nonprofit organization?  

It's not just about having organized, meticulous accounts.

Plus, there is something called non-profit member based Associations of Land Lords.  

I have worked over many years experience in a non for profit organization with rehabs and new builds well over $30,000,000+. although i have not seen every transaction through. i have had many contracts, construction contracts, city and government reporting and many small community projects come across my desk.

I have been using mind mapping software to help me finalize my 2015 goals, my organization structure, my business plan, etc.

@Kevin Davis - You may have better luck networking with attorneys organically.

Usually if it a large HML institution they will do all of it but if you can find an individual or smaller organization, maybe not. 

I have sent them email asking them to pay immediately plus late fees or I will have to move on to evicting this tenant due to their organization not being able to pay the rent due for 2 months.
