How I could live and work in Miami ?

I am from South Africa. I operate in sales for any alternative energy diesel generators solar systems and so on . I am visiting Miami so I am on a B1/B2 visa. I would like to investigate how I could live and work in Miami. Any help would be most welcome. I am 57 years old. Fit and willing to do most anything I am single so don't need any fancy things. Can somebody please advise

I think your experience in sales could give you a good start in the USA. They always recruit B2B sale executives and you seem a good fit. I hope you will get more advice, this is what I've learnt so far.
