Need advice from GOM guys

I have this dilemma. After sailing electrician (SIU) for the last 5 years I want to upgrade and get my 3 A/E, but the problem is that if I sail 3rd with AMO I’ll be taking a pay cut (which I can not afford). My question is. What position can I get with this kind of license in the oil fields? and what kind of pay I can expect? Also, do these companies pay travel? I live in puerto rico.
