@waqas, brother their are numerous fields. You can get a job from photo editing to programing, web designing etc. There marketing and translation jobs, administrative jobs like virtual assistant to name some. Personally i was hired for marketing and sales of VMWARE products. I was asked for skype interview, selected. Before taking assignment i was trained. But i left that job due to personal issues. Regarding earning there are many pakistanis. Check their profiles and you will be surprised to see their earnings.

@zernab, thats why i told you about odesk, freelancer and elancer are a bit shabby.

One thing more never take any job outside odesk or any site interface. For payment surety do jobs in site intereface.
