Seek out someone who is and shares your vision, and screen for agents that work with expired listings since that is what you personally want to work on (note that this is a tough market and takes a thick skinned agent and not all will do this as a result). 

I ask them questions and I want to see their facial expressions.

Get a tougher skin. 

They have more skin in the game then you do.Make sure you get clear title.

How do we know who is making these calls and where they get their info....do they have any skin in the game?

You either need to be in the market where you are investing or have a trusted 'boots on the ground' partner (who preferably has skin in the game) to be able to invest remotely.

In your case, you have a decent amount of skin you can place into the game which should satisfy most lenders.Make sure you get fully educated on the process of rehab flips and how to get your acquisitions.

While it is possible to do deals with none of your own money, the more skin you can place, the better options you will have.

I'm talking about "nonverbal communication"what your facial expressions and body language say can be opposed to what year word center saying.If you watch the show Colombo with Peter Falk, you'll see the actor use his face to convey certain emotions.If you make your eyes look big, you make yourself look naïve and innocent, which is nonthreatening.If you have a scrunchy face or confused look, you usually have the seller feel like they need to go into more detail.

The more skin in the game, the more return on investment.
