Courthouse Marriage!?

Hey yall! I was wondering if anyone knew where to go to have someone ordained offiate a marriage? Fiance and I plan on getting a marriage certificate next week as we wanna be married before the baby comes; but I just learned the place doesn't have an officiant on hand so we'd need to go elsewhere. I'm not too sure where to go and heard judges don't typically take same day? Idk, all kinds.of confused but trying to get it done all in the same day so any advice is appreciated!
