What are ways that we can find contractors for weatherization to partner with? 

Each state has weatherization programs in most counties. The state of washington weatherization program is located in the Stare dept. of Commerce. Each local agency has a group of contractors or they have their own workiers.

One of the challenges we have came across on our intervention is enrolling participants on these local weatherization programs because a number of these participants don't meet the requirements; i.e. legal residency. Have you had any similar issues and what are other options or suggestions do you have? 

We did have similar probalems including illegal duplexes as we worked with local permitting agencies. We just had to drop them from the hh work. I share your pain.
