Auto Blending a batch of photos [Scripting help required]

I am trying to automate the production of real estate photos. I take two photos-one for outside exposure with flash fill and one exposure for ambient room light. I place both photos in one document, select both then select "Auto-Blend Layers". This gives a good result, rendering the outside view through the windows well and revealing detail in the shadow areas of the room , while minimizing the flashy look.

I am seeking a batch recipe to automate this process. I don't know how to get the program to go down and slect each pair of photos, perform the needed action, save and then go on to the next pair.

Thanks in advance for any guidance!
