Opportunities at freelance Sites
World is becoming small with job opportunities coming your way.
If one has the knowledge and desire, then it is matter of time before work haunts the desired. Register at any of the freelance sites like odesk.com, elance.com, guru.com, freelancer.com, vworker.com, skillpages.com etc. and take online tests with the respective sites or with other sites like brainbench.com.
Go through the job listings in your area of interest at the sites (find job/search job). While going through the listings, you will come across many terms, software used, websites,etc. which you may not be aware of.
Do some trial project just as specified in job listings. This will give you the confidence to apply and get interviewed. Do not bother too much about the rates at the initial stages. Initially one has to build a portfolio with job history.
After working on small jobs for a few hours, one can slowly increase the rates. In a few months, it is easier to command respectable hourly rates.
