I have been working in the East Coast for a few months and I did well . Now I want to try West Coast , my time in the US is limited so I need to be sure if going there will be a good decision . It seems that  there are better quality for less price and more competition , It is true? In terms of money is better for a provider in general working on the East

A few threads down, you asked a question and quite a few people took the time to give you serious and thoughtful answers. It isn't required, but it is good manners to at least thank those folks for their input... before you ask another question.

to learn to be humble.

Lol I didn't tought it was a big deal to post a message just to say thanks , I did it in the past when I ask other question and TER delete my thanks post :/ , but  anyway you are right ! Tahnks so much for all the answers and great help
