Church Girls- ceremony music

I need some ideas/suggestions for music for the wedding- we are having a full mass (possibly unity candle and also flowers to the blessed mother).
Also if anyone knows of a website that I could listen to clips, that would be awesome.

as of right now, here is what we chose:

Processional: Canon in D (and that is for the entire BP including myself).

Responsorial Pslam: It's not going to be sung, but read - The Lord is Compassionate toward all his works: Pslam 145

Presentation of Gifts: Ave Maria

Recessional: TBA

Unity Candle: I don't know if there is music played during this but if there is we have to figure that one out.
