Isla baby girl name

Hi! 
My husband and I love the name "Isla" for a girl. (Prounounced EYE-LAH) 
However, I hate the fact that some  people will probably think it's pronounce "ISS-LAH". 
I know someone who spells it "ila" but that's hard because when capitalizing the "i" it looks like "LLA" ---> "Ila" see? 
Help! 
Do you think "Isla" is fine and most people will know how it's pronounced? I guess not many times will people be reading off a paper... except for teachers I guess.
