Aww congratulations on your initiation!! I’ve actually already featured Chi O as sorority of the week. Enjoy your initiation!!!
Congratulations!! Do not let that inhibit you in anyway. I would definitely advise you to get in contact with your inter/national headquarters (there should be someone assigned to your chapter) to see what things you should be working on. Also, talk with your advisors. They know what things were being done previously to give you some insight into what your roles will be.
The best place I know of is Herff Jones. They are great quality and have a ton of options!
The best advice I can give you is that recruitment is all about your choice. If you would rather attend ABC’s event, then go to ABC’s event. XYZ members should not get their feelings hurt. It is recruitment and they understand this. It may seem strange, but do your best to keep your friendship with XYZ members as real and honest as possible. All you are doing is exploring all of your options. If they truly want to be your friends, they will accept that.
