The standard way to balance the game (However, usually towards the US), is to give the player some number of influence they can place anywhere they already have influence at the start of the game. I think this works slightly better for the US, since they can often add it to Iran, making a coup that much harder, or add a couple to France and try to score Europe quickly.
Depending on the advantage you want, I would suggest trying something like give her Iran to start instead, which would basically act as a 100% successful turn 1 coup. This way it's not a totally unfair or out-of-band start, it's more just forcing her to have good luck at the start of the game.
