Applying for job overseas

[Niki Nono]

Hi
I am working in a reputed company in Mumbai, India and am looking to change my job.
I was considering the following options
1. Shift to a better salary somewhere in India
2. Search for a job in UK and then move there for some years - Need information on how I start applying for jobs, I know about the HSMP thing, but then how do i apply to companies in the UK sitting in India?
3. Search for a job in Singapore - Same thing, how do i search for a job there sitting in India?
4. Canada and Australia - Same thing.

Basically I want to know how to start the process of searching for jobs overseas, all places except the US since US has the H1 thing which is pretty difficult to get considering the number of applicants.
Please let me know, any links to consultants, etc that someone might have used and are satisfied with their help.

Thanks in advance, looking forward to your replies.

What is your skill set and experience? The best option is to register in job sites and selecting preferred location to either UK or Singapore. It worked for me!

Sai, where are you currently and which sites did you use?
I have 4.5 years experience in Java (SCJP) and PLSQL, currently studying for SCWCD to enhance my skillset.
So what do you think are the possibilities and what route does one need to take?
