I agree with the above. This is not a good situation at all, this is why in the future, always have the tank up and cycled before ordering the shrimp. But for now, try and stuff the temporary tank with floating plants and fast growing plants and use some tank water and you should be ok till you can get the new tank setup. Just test the water on the temporary tank often to make sure Nitrate doesn't get too high.
