A pitcher pump will work if you are satisfied with carrying water from the pump to where you are going to use it.
You can also get pumps that will pump to an elevated tank that will provide enough pressure for toilets and faucets but probably not a real shower.
If you have a hill it is possible to make a nice little water tower to pump to. I would keep the tank small so it doesn't have a lot of stagnant water.
A pressure tank would not be a good choice because there is so little effective drawdown and somoeone would have to pump it up after every 5 gallons or so of usage.
