Information before purchase Dashboard Admin, Modo with update of the database

HI

sorry for my bad English.
I do not know if I have to post here.


I would like to find a script or rather a dashboard for admin and moderator with the possibility to add entries in one of my tables in my database.

I am ready to buy it because I do not have time to learn to do it all and I do not want to do it.

I would have liked something like this:
https://codecanyon.net/item/php-scrud-da...6?s_rank=8
or this
https://codecanyon.net/item/php-dashboar...l/19248072

but I would like to know if it is difficult to code? because I imagine that I will have modifications to make so that it is as I want it.

I am not an expert I manage and I learn.

I would like a moderators management, a login page to the dashboard.

I would not be wrong before buying it, I inquire about how it works to see if I can change it, and which one to buy.

Thanks for your help
