AB or 3rd mate NC

I have my AB ticket and was wondering if OS time counts towards your license requirements. If it does then im less than 8 months away from my 720 days for my Limited near costal 3rd license. What is the going rate for a NC 3rd and does AMO have any positions of this type, if not im in the Tampa bay area if you know any companies that would hire in the future. I know its a loaded topic but, trying to see if its worth sailing 3m Limited until i can sit for 3m unlimited, Thanks in advance.

See 46 CFR 11.407(a)(1). The time that is not required to be as AB can be as OS, provided it is all on vessels over 100 GRT.
