Create a system to evaluate astrophotographs based on human input. I have ideas for implementation but need stats help.

I am looking for help creating a system that evaluates astrophotographs based on human input. The primary goal is to pick the best from a group of pictures, with more than 500 astrophotographs being evaluated daily. I have ideas for implementation, but I am open to suggestions when it comes to the statistical methods used in the evaluation process. Therefore, I need someone who can help implement my ideas in a practical and efficient manner.
