There might be a time when you contact a translation company and they say their translators are busy and cannot start your job right away. Even if they refuse you, you should appreciate their integrity and frankness. We recommend you contact them again when you have a job to do next time. However, never beg them to help you by inserting your job into the queue - that would break their process and overload the translators, either of which would result in a very poor translation.
