the pressure switch, is the one tapped into the high side pressure hose, correct? unplug that and use a wire to jumper those two connections in the plug. the compressor should kick on, and then see if your getting cold air in the cabin...
if so, clogged orifice tube? bad pressure switch? do you have a set of gauges? does the low side have an over-charge condition? I'll be the first to admit, that if you have exhausted all means, it might be time to take it to a specialist... I know, labor costs what they are, but A/C is worth the comfort, and if it is something internal, the cost of the shop is almost what it would cost to purchase 134 and re-fill the system.
