If you can have a well for irrigation have one installed with an electric pump and make sure that it is plumbed so that it is easy to remove the connection to the electric pump and install the hand pump or it might be possible to plumb it in with valves that would allow you to choose which pump to use.

On my shallow well it takes me about 15 minutes to disconnect the electric pump and install the hand pump. Haven't had to use it since I re-plumbed the connections when replacing the electric pump. But I have it if I need it.
