I have a brake bleeder pump with pressure indicator so I get I will need a fitting to pump air in the low pressure valve of the A/C system. Please correct me if I am wrong.

No. You need to pull a vacuum on the system with a set of AC gauges and a vacuum pump. Then, you need to see if it holds vacuum for at least one hour, preferably overnight.
I am not vouching for this specific setup, but something like this:

You may consider buying a postal scale and a cylinder of R134a. It'll cost about the same as paying someone to charge it.

thanks man. I will look into that. Since the car will be disassembled, I will make that procedure with the engine off (compressor turned off), or should I start the engine as if I were to charge the A/C System?
