I bet there is plenty of coverage there for LAX already. In my impression, services like this (and even Flightradar24) at this day and age are mostly interested in coverage in spotty areas in rural areas and far away from civilization.

Don't get me wrong! I'm not trying to demotivate you. Just letting you know that maybe they'll turn you down. However, even if they do so, you can always learn a lot by doing so... and it's quite cheap, and redundancy is always welcome, right? :)
