Is the chess club organiser supposed to be a player too? Why can't you run the club without representing?
Advice Needed / School Chess Club
The key here is whether you like to play chess or not... not how good you are.
If you like chess, then you'll enjoy running the club; otherwise, you'll probably be very bored watch club members play.
As for having "president of chess club years x, y, z" on your college application, frankly, I don't think it'll help in any meaningful way. So, you can go tell your dad this (should you not like chess and don't want to watch boring games for an hour after school; it's just a waste of your time).
If you would like to help your friend, work on mangement skills, and are motivated to start this club---then go ahead and do it. My friend and I started such a club. Though he was not very good, he really built up the club. That club is still there today. When you have any kind of club, most people just want to attend the club. Without a dedicated manager, all clubs die. Good luck.
To quote somebody
One if the biggest myths and stumbling blocks about starting a chess club in school is the belief that it requires a chess expert. It doesn’t. It requires someone with good organisational skill and no more than a very basic knowledge of chess.
Such a person could be a teacher, TA, parent, grandparent or a volunteer from a local club (with all of the usual checks in place, of course).
Here are the things they you need to learn that are not hard to learn.
TACTICS
For beginners the most important aspects of chess that they need to study is tactic. The concept of tactics is easy to learn(but getting better at it is another story). Pin,fork and discovery are example of tactical themes. There are also different checkmate patterns. Solve tactics problems. Once you learn about them, you can teach the different tactical and checkmate patterns and once they learn the pattern, you can give them tactics problems.

Once you study the links i have shown, play games here at chess.com. Don't worry about defeats, learn from your mistakes. Play at 15(or more) minutes time control here.
For supplementary materials for your clubs, you need materials for chess tactics puzzles that they can solve. You also need chess clocks and chess boards.
