dude, u dont need no pads...
I am literally a pioneer of rugby in my old school,
the most important ingridient is ofcourse, some maniac ruggers like yourselve! you need atleast 4 or 5...
play rugby during breaks, get people to know the sport, see the sport, feel the sport... in my case, we played rugby at break time, ripping our uniforms, injuring loads of people... our headmaster was ******, so he said FINE we'll make a rugby team!!!
we got rugby balls... LOADS of rugby balls.. (get around 6-8 first)
cones.. well ur PE dept must have them already...
GRASS pitch.. lol.. the grass was out of bound for us during break time.. we had to play on astro turf.. hence the injuries... lol..
and tell the team to get mouthguards... any shirt, any shorts at first... get sponsors for your uniform.. but before u ask for one, prove them that u can play! in my case.. we played against this school who has played way more rugby than us... in our first ever game, we won.. a close game but we won.. now that sends a good impression for the team!
