US companies hiring pilots from abroad?

Hi
I am a Commercial pilot with 1500 hs tt (40 multi), most of them flown
in Florida as a CFI. I am from Argentina and I came back here after
the J1 visa I had expired.
I have heard from several pilots that the aviation industry is
starting to pick up after the crisis caused by the 9/11 attacks.
Does anybody know any aviation company that could use my services?
They would have to help me get a working visa but they wouln´t need to
worry about me going to another company after six months as it used to
happen.
Thank you

Anibal
