Once again safety first! Regular inspection of your tank is and can be a life saving measure. Always check your hydro dates and maintain those inspections too!
If you have the ability to rent a full size tank, do it! They come right to your door an a big truck (based on your usage or consumption of air/nitrogen). Once you've got the tank all ya need is a regulator and a couple shut off valves a gauge, and a npt fitting.

In this picture you see the entire station, the reg's coming off the tank, right under the reg is the bled (bottom yellow handled shut off valve) valve. Above the reg is the tank gauge and the tanks on/ off valve. And the all important npt fitting.
