Strewth...You said that you want to get into the US and build your hours. Well, you have several options available to you, but you will need to have some money saved up and ready to spend (especially considering the exchange rate at the moment).
1. You can enter the US and work under a study visa, this is usually through a flight school that will sponsor you. You will need to conduct your training with them, commercial conversion and instructors. Then they will employ you as an instructor and pay you (the hourly rate is alot better now than it was when I was there), and you will probably depending on the flight school do max hours and learn alot. It is a two year visa, and you will do alot of single and multi engine instructing.
2. When your visa is nearing it's running out stage, you can start studying at a University for an Aviation degree, and continue to work and live in the US, while you do this. You are not tied to the same flight school at that time, and can usually try and find something doing air charter and the like.
3. You have a very very very slim chance of finding someone that will sponsor you. Your other chance is there are some businesses in the US that will employ you in the right-seat, to be located somewhere around and fly business jets around. The only catch is the $40000US upfront for the training. You do get paid during this time though.
I hope this helps a little, if you want to ask about anything else, email away!
