Batch Import and then Export of scaled Graphic

Hi everyone, I have a directory with dozens of metrically scaled OBJs in it.

I'm looking for something to do the following:

Import the first OBJ
Next to the OBJ needs to be a metric scale bar
Export out a view port image looking straight down on the OBJ with metric scale in view.
The exported view needs to have the same name as the OBJ but with .PNG extension
Remove the OBJ
Load the next OBJ in the directory and REPEAT

Is there anything out there that is similar to this that I can modify? If the price is reasonable, I'm also willing to pay for it.
