Many people online have the ability to offer their services at an affordable price. These days, quite a few people are offering translation services in a number of languages. Australians find this to be a good deal because it is usually much cheaper then other services out there.
There has always been an opportunity to have a translator work on something. Before the Internet, it was just much harder for a person to obtain services like this at an affordable price.
In most cases, a simple program on the computer is not going to provide the same type of translation as someone who is a real human being. That is because language is not always completely translatable on a word to word basis. Using a human to really understand everything is going to be the best way to go in order to see a true translation.
