But now she tells me she doesn't have the money because she lost her job. 

I once rented a place way under market because the tenant told me she really couldn't afford any more.

(Take it from someone who has learned by putting their foot in their mouth in the past acting out of emotion and truly regretting it even though it probably didn't mean much to the person I was speaking to.)I think that referrals from other investors are a great starting point to find someone who you might mesh well with.

I have not heard from her for about 15 years, but the last time I spoke with her she asked me to give her a ride to Victorville California (120 miles from Los Angeles) because she purchase a property in Victorville and she told me she had purchase a $550k house in Las Vegas. in fact, this was just before the market crash in 2008 and I never heard from her again and really don't want to because she was fairly petite, cute and used men to get cheap and free services with no intention of paying back in any way.

She told me she would not be able to put an offer in for me as it's unethical?

I would guess your are wanting the lowest level of protection like Level 1 (stops 9mm) or Level 2 (stops 357mag), If this is wood construction, the walls will need fiberglass mesh panel, basically Kevlar about 1/4" to 3/8" thick or you can use 1/8" to 5/16" sheet steel to clad the house.  

Last month, she informed me she was leaving the PM company due to health issues and that another PM would be taking her place.On my first invoice under the new PM, I see a charge for $100.

You can cut the cleat on the rake angle and router a design into the edges if you want to get fancy.

You internet hub/router can't do that either.Yes they can link cameras to it and I suppose microphones.

I told her flat out its a scammer if she had not talked to me she would have lost who knows how much.So not trying to blow anyone out of the game or the water but what we described is real and its how the scammers work..
