i find new skill system , not kopi RU plugin 

Perhaps ZLevels Remastered fits your needs.

no it is not exactly what I am looking for, I use skill but wreck modified RU plugin + discount. That's all I want to add to one skill plugin. + Maybe some functions from rpg system. I have some of my own suggestions, I am looking for some dev that can do it and do a good skill plugin, I pay and I don't want it as a privat, it can be sold,
