Hi, I can build this script, I have done similar things before, importing programmaticaly content into K2 component. The script will work exactly as you desire: will update content if is already there with a older date, will insert new entries, create custom fields if this will be necessary. I will deliver the script in two days, then you will be able to test it, and if you will find any problems, will be fixed in next day.
