Here’s a list of outsourcing websites to free up your time (and lower costs) so that you can concentrate of what really contributes value…
- Brickwork India
- Fiverr (a lot of value for just $5)
- TaskRabbit (for day-to-day tasks & errands)
- UserTesting and ClickTale (for website usage and usability)
You can outsource (almost) everything to (almost) anywhere, and have your virtual assistants and free lancers ready to help you.
One of the experts on the topic is Tim Ferriss… Tim explains well in his blog posts and his book that outsourcing is great but has some pitfalls, mainly related to mismatched expectations (clarity of objectives) and communication (taking things for granted) in delegating tasks to others.
I also suggest this great book that analyses in detail opportunities and threats of the world getting flatter and flatter:
Thomas Friedman – The World Is Flat
