I use Zillow for the initial call and if we are in the same ballpark range to proceed with seeing the property, then I will pull MLS comps for the appointment.  

I tell them to call me 30 minutes (how long it takes me to get there) before the appointment or I will not be there.

It was not only a struggle to find qualified contractors that weren’t crazy expensive, but it was also difficult to find contractors that would show up on time or even come to the appointments that were planned.

Since she is a dual agent, maybe try an appointment with her managing broker, bring a letter in writing and be prepared to discuss that you felt you were pressured into making the offer with the high earnest money deposit and no contingencies (especially if that was the agent's idea and not yours) and that you feel the agent should have pointed out the high-power wires so close to the property (although since they are right there, you probably should have noticed them yourself so not the best excuse), that apparently there were many offers so the seller should not have much trouble selling to someone else quickly and that you want the contract released with your full deposit back due to feeling like you were not represented to your satisfaction and didn't really understand that she was not representing your interests.  

At $8-10/hour I would like to pass the initial call/appointment setting off to a VA to free up some of my time.

As soon as I get a notice, I let tenant know the apartment will be listed for showing, I set appointments and give tenant 24 hour notice that I will be showing the apartment within a 2 hour window, the sooner shown the sooner rented..I don't do a open house, I do only by appointment.

Scheduled appointments with Contractor and sent them the scope of work ahead of time.  

When a buyer or seller is hot ... close and sign, make sure your appointments are made when all parties are present too, otherwise they turn cold and blame it on the one who wasn't there! 

More value assets, including real property, may require a more formal probate process and the appointment of an administrator or (generically) a personal representative.
