Looking for RPG publishers to introduce my script

[Randomer10]

Hello.

I have recently finished making my own unique setting for a roleplaying game,
where it is over 100 pages in a document which describes classess, skills, spells, and such. But it does not have any details about any plot or quests, so it is more like a foundation (similar to D&D rules, but without any statistics of engagements).

Do you know what RPG publishers I could present this too and whom are the most reliable. For this could both be an idea to a computer game and a table-board game.

I apprecicate any assistance.
