Getting a shiny Pokemon is dependent on luck. The chances of encountering a shiny Pokemon is 1/8192, so it may take a long time to get a shiny Abra.
You can get a shiny Squirtle. The most reliable way to get a shiny Squirtle is to repeatedly hatch Squirtle eggs. This process will take a long time however and could take hundreds and hundreds of eggs.
Well, your chances of finding a wild shiny pokemon are 1 in 8192 sooo to answer your question... a VERY VERY long time.
Yes, shiny Pokémon stay shiny after evolving, as long as it is a legitimately caught Pokémon (e.g. not caught by using codes or Action Replay), and usually even then.
