The Catholic marriage ceremony does only take about 10 minutes.  If you hold your wedding in a Catholic church there is generally a mass, which takes the remainder of the hour.  However, in order to have the Catholic marriage ceremony (which is what is required for the church to "bless" your marriage) you and your fiance will need to go through Catholic marital counseling.  This generally requires meeting with the priest a few times  for two to three hours at a time.  A Catholic priest cannot perform a church-sanctioned marriage ceremony outside a Catholic church without the explicit permission of the bishop, so having him co-officiate is probably not an option.  You would in fact have to say your vows again, although they would not be "your" vows - the Catholic vows are a prescribed part of the ceremony and are not rewritten (as other churches allow) to suit the bride and groom.

You and your FI should definately call the offices of your local Catholic church and arrange to meet with a priest.  If you want more information, there was an (extensive) post about the essential impossibility of having a Catholic ceremony anywhere but in a Catholic church a few weeks ago.  I would warn you (as someone who was raised Catholic but WILL NOT have a Catholic wedding) that you should look carefully at the vows before you decide what to do, and make sure that you feel comfortable with the agreement you are making.
