Searching for Property & Team in Milwaukee

I'm in the middle of searching for my first investment property in the Milwaukee area. I'm looking for a multifamily property with a max price of 150k. Ideally I'd like a 4 door property but 2 or 3 unit i'm open to as well. 

From listening to the podcast I keep hearing that networking and talking to other local investors helps you in many ways and since I'm new I'd figure I'd throw out a line to see what comes back. 

Here's what I'm looking for help with: 

1. Is anyone is aware of properties not listed on the MLS that I should be looking at in the area?
2. I'm based on out Chicago and will need a property management company sooner rather than later. What are some good ones you've worked with especially for investors with not a lot of property? 

Thanks in advance!
