Few Online Work Arrangements
Manage sharing documents through collaboration tools such as MS SharePoint, Qontext, and online storage like SkyDrive, even Google Docs.
Apart from these, here are a few online freelance companies as shared in the article "Working with Talent Markets – oDesk, Elance, Freelancer, Guru, vWorker."
oDesk
oDesk is the leader by volume, a VC-funded, Silicon Valley operation. oDesk pioneered hourly payments and handles the most hourly deals. They also introduced the idea of time-tracking software that takes a picture of the worker's desktop every 10 minutes. This innovation has been controversial, and some people see it and other rules as overly controlling. However, it does help oDesk guarantee payment to workers who track time this way. They have a lot of "affiliates" - individuals who work for outsourcing companies.
Elance
Elance is another VC-funded, Silicon Valley operation with state-of-the-art software and Web UI. They have attracted a big following of outsourcing companies that use Elance to find and bid on jobs. Outsourcers have not been the best source of talent in Assembla's tests, but if you are looking for more of a packaged experience, Elance providers can deliver it. Traditionally, their jobs were fixed-price, but Elance now matches oDesk with hourly time tracking and payment. Elance offers an API and a low $750 buyout price, so there are now more ways to use them effectively.
Guru
Guru is unique because it has a lot of US-based providers. The other exchanges specialize in lower-cost "offshore" workers. Guru has more providers in non-coding categories like design, writing, and business consulting. They have more individual contributors, which have been better in our tests. If you want to work with individuals in the United States, you should look at Guru. On the other hand, their contracting is primitive and limits the ways that you can integrate team members. They only offer fixed-price jobs with no buyout option.
vWorker
I have been using vWorker (formerly Rentacoder) for ten years, and I used it to find several of our core team members, including our chief architect, who is now a partner in the business. It is still mostly a site for small, fixed-price jobs. The strength of vWorker is the huge community of individual contractors, many of them "offshore," who are available to try out on small jobs. vWorker does not have a buyout option, and their communication rules are restrictive, so in the past, I usually used it just for advertising, an obscure option that they called a "bulletin board" ad. However, with the new hourly payment option, it can fit into our qualification process.
Freelancer
I like Freelancer (formerly GetaFreelancer) because of their unbundling. They don't force you into any particular business model. You can get a fixed price, hourly, or just buy an advertisement, which they call a full-time project. Freelancer is a business from Australia that has been quite aggressive about adding new sites and features. They claim to have 1.9 million registered workers. Freelancer does not seem to offer any protection for workers.
