As for your fish, I would just leave them for the 2 weeks. I'd do a bigish water change on the day of leaving or the day before and then leave them with the lights on a timer.
If you are unable to bribe someone into feeding them for you, you could invest in an automatic feeder.
i got an automatic timer to feed my fish while i was away and had my neighbors come just every coupkle days to give them treats like bloodworms. one thing with the automatic feeders i have seen is you cant close the lid of your tank. so if you have anything that will jump thats no good. also the evaporation from leaving the lid open was crazy.
