Change file name

Hi everyone,
I have the following problem; I own quite a lot of file names, but there is a difference that they are with last name first and also with first name first.
So now I want to move the part of the filename before the comma to the place for the separators. Here are 2 lines with the file name as it is and as I would like it to be, with a side note that the part before the comma varies greatly of course

Old: Baudewyns, Benny - Het madagascar debacle
New: Benny Baudewyns - Het madagascar debacle

Old: Bateman, Jackie - Dorst
New: Jackie Bateman - Dorst

There are 2 fixed places it should be based on;
A: everything before the comma is the last name
B: Before the separator ( - ) the last name must be placed back.
If no comma is present, the entire file name should remain.

Does anyone know what string I should use to get this done?

Thank you in advance.
