HACS is good company, but search the other guys, (WASINC, SIGMAR, IAC, etc...). Basically they all advertise the same jobs but all offer different pay, medical, and other benefits. So search each company and see what they offer.
I think Frieght Dog made a page with a lot of the Contract companies. Thanks for that!
Also JAL medical is sometimes strict. Knew one guy that was heathly (in my opinion and his), but didn't pass it. They checked everything including BMI, Body fat %, vision, blood pressure, EKG, and a test where you blow into a tube. Similiar to a NZ/AUS medical I think
