Pre flop I would have raised to $2.25 which isn't a lot different but may get rid of one of the callers.

I think you push here and hope they are on 10's to j's pp or the nut flush draw. AA unlikely as limp call (UTG is a bit scarier if they are slowplaying at an aggro table - but you don't have that info) suggests pp but not premium... worst case you are up against a set but with your stack size you are already pot committed in my mind.... could be against hands like A8s but at least you have one of the flush outs... and if it comes down with two spades you are also in alright shape with 2nd flush.

So push and pull down a K on turn and then pair the board on river.... collect big pot.
