What events could I do

I come from a chapter that really only has the funds to do a formal each semester but not do things w other Greek houses, I am a newly initiated brother and am hoping to take over as social chair but I talked to our current one and he said we really don’t have the funds should I work with our philanthropic chair and do some fundraising events or are there any “free” event ideas you guys have. I’m trying to make my chapters presence more noticed on campus
