Update
For those who looking and didn't have a link like I did, here's what I did and maybe you can try as well:
1) Your cover letter and resume isn't as great as you think it is. Research cover letter and resume writing tips to improve your impression. Updating my cover letter and resume was a development process and took a couple years. After many hours of research, these documents start looking good to you. However, they really aren't that great, especially to someone else who's looking at hundreds of resumes each month. To address this little hurdle, you can employ the services of a professional writer to assist ~ $1,600. See it as an investment.
2) Also invest in some pretty paper for your cover letter and resume. I spent around $500 for the number of documents I sent out.
3) Get a telephone directory or check
http://www.energyguidett.com/, start from A and work your way to Z. In one month I mailed and emailed at least 60 applications. Most of them were not responses to vacancies, but more for the company to have on file. Most vacancies aren't advertized. Some companies also "renew" their applicant database every 6 months, so send out more in 6 months if you aren't successful. Check the newspapers everyday and look out for vacancies.
I called every company before sending the application to get information that will allow me to tailor my cover letter to the HR/Department person, and to also verify address and phone number.
If you did not get a reply stating that your application was received, call to follow up. Don't assume the mailman delivered it or their email server was working.
4) Register on websites such as caribbeanjobs.com to get email alerts of new positions. I even registered on international sites such as monster.com to widen my reach. Research international human resource recruitment sites and send applications to them as well.
5) Wait.
If you're really under a rock, you can apply for other jobs as well that are not in your long-term sights. At least you can get an income while you wait. I worked at a small store building computers and selling stationery, and outside to that, sold flash drives after work. It was a real cool scene too. I was able to network and learn how to deal with people.
In addition, the best thing you can do is to increase your network. Your aim should be to increase the chance of success for every opportunity that is available.
