hello every one!
you have mentioned nice sites for freelancing and getting an opportunity of earning money without making high efforts. The trend of outsourcing and of virtual employment has been increased tremendously in recent 1-2 decades.And i think that it will definitely capture major employment market.But the major question is "reliability".virtual employees are reliable or not ? it depends and vary from place to place.
Indian outsourcing services are really highly reliable and very cheap also.So it's always better to cross check about virtual service providing companies.
