Jacob, I understand that your money supply is tight at the moment, but I still advise you to give Fuji Provia 400X a shot (or 36). It is ISO 400 and can be pushed to ISO 1600 without problems. It is the only slide film I would recommend for evenings or night scenes.

Note that candle lighting looks very romantic to the human eye (which does a lot of in-brain color temp correction) but rarely looks good on slide film as is. I highly recommend you use fill flash to both tame the contrast (night scenes are generally very high in contrast) and to get somewhat normal colors.

Use the flash at -1 or -2 stop flash exposure compensation and make sure the non-flash exposure is correct to get good mood. With ISO1600 you should still have plenty of background in your image.
