How to improve my chapter's visibility and get recognized?

Hope that this is in the right forum:

I'm from a rather small chapter of a national fraternity - but it is not recognized at our school. It has been around at the school off-campus for over a decade.

When we wear our letters, we get stares and comments. Some GLOs may know something of our existence, but most don't. Of those who know us, our reputation isn't necessarily a good one and there has been some bad blood between us and the school in the past.

How do we boost our recognition and get a positive image on campus? We can’t advertise on campus.

How do we get better relations with the other GLOs and would they be receptive and helpful to us, given our situation?

The school may be doing Greek xpansion soon, so we would love to finally come on to campus. How do we better our chances of being picked? We have attempted in the past to no avail.
