I would say good luck on trying to find cheaper flights, they are really expensive no matter where you look really..
They ideally would like you to have already booked your return flight due to immigration etc, you may want to look into this a bit though
My advice would definately be to save for this trip as just going there and not being able to do everything you want to could be quite frustrating...
I hope you don't think I am squashing your ideas I am just giving my opinion
