You need to diagnose your system to determine what is wrong. The easiest test is to jump out your low pressure limit switch. It is usually located close to the accumulator. If you jump it out and the compressor comes on, it is a safe bet that you need a new limit switch.

You do have the compressor On while you are charging the system, right? Since you have 30 psi with the compressor off, and 0 psi with the compressor On, this tells us your compressor is working, and you are nowhere near charged. Keep filling, until your low side gauge indicates full/normal charge. Do
NOT overfill, it won't get cooler. It would get warmer and it will
eventually damage the compressor. If your system was evacuated, you may need anywhere from 3-5 cans of Freon to fill the system, depending on the size of the cans. If your lines are freezing, there may be a restriction. I hope you got all the moisture out before charging, by pulling a strong vacuum in the system. I also hope you didn't release any old freon into the air.
If you are not EPA MVAC Certified, and a standard recharge isn't fixing the problem, I recommend you get an EPA MVAC certified technician to fix your A/C.
Also keep in mind that the only accurate way to charge an auto a/c
system is to safely and legally recover and evacuate all the existing
gas from the system, then hopefully after a successful leak repair,
carefully weigh-in an the exact amount listed on the a/c factory
specification label placed under the hood by the factory to assist the
service technician, which, again may leak-out if the needed repair is
not performed properly.
