Once you have found the right translation services then you should ensure that you are very happy with them before they start work
. If you want them to stop because you are unhappy then you should speak to them about their services. If it is a large job then you might ask them to complete some of it so that you can check that you are happy with it before continuing. You will select your translation services based on price but you should consider spending more to get a very good job done. The cheapest company isn't always the best one to choose and you have to look at all of the factors before selecting the one that you want.
