Looking for 114PCD alloys

So me and a couple of friends got invited to a Auto show to showcase our custom built buggy. And right now we need to replace the wheels. So if anybody knows a place where we could get 114.3 PCD wheels (anything between R13-R15 would do), let me know. The budget's basically non existent at this point, keep that in mind. Side note: if anybody's willing to sponsor the build, lmk.
