I think the answer depends on how much money you have and are willing to spend. If you have the money to do the multi and build the time probably talking at least 5 grand assuming you could split most of that time... then do that and skip the CFI. If you don't have the money, then either keep going after the CFI the slow way or go find a accelerated program. The CFI is good b/c you'd probably be able to keep you gate agent job while making enough money on the side to buy the multi time. And as a bonus you really learn a LOT about flying from flight instructing...you'll be shocked. Either way I think with those times you can probably get hired somewhere but it won't be Republic, Skywest etc. Best of Luck.
