Can i request help in adding all information to a series?

I found the title "https://www.imdb.com/title/tt20751556/?ref_=ttfc_fc_tt" and noticed that a lot of information is missing. A lot of actor's credits missing, directors and writers. I would like to add this information very much but i don't have time to update every episode. So i wondered if i supplied a linl to where all the relevant credits of each episode can be found, i could recieve some help in adding all this info?

Here is a list of all episodes and assosiated credits.
