The first thing that you should endeavour to do, is to hire services through a well-established translation company or through a well-established job hiring service. Doing this, rather than hiring an individual will make the job easier for you because you will not have to verify for yourself that you have hired the right person. If it is your first time hiring someone for the said job, then it may be daunting and uncomfortable for you to know exactly what to do to hire a trustworthy and qualified candidate. That is why it is better to take the headache off your hands and save some time as well, by using the services of people who have already created a reputation for trustworthiness in translation. English to Spanish translation,for example, should be done from a company that is experienced in translating English to Spanish. That way you can rest assured that the translation job will be properly done and all you have to haggle about is the time to translate the job and the cost. However, a few of the other important steps mentioned below will be important.
Additionally, whether you are looking for professional translators with a reputation or not, be sure to find out if they have certificates or documentation to prove that they have been professionally vetted to do the job that they say that they can do. If you are looking for Spanish translation for example, ensure that a Spanish translation authority has vetted the company or individual to translate for you. This is an important point because doing so will assure you that the little nuances ina language that could drastically change the meaning when translated, will more likely be caught by someone who has gone through a rigorous training program or vetting program to ensure that they can do a translation job very well. In the same breath, it is important to hire for the exact job that you require. For instance, many people often fail to realize that translation and interpretation are different jobs and furthermore that they require a different set of skills to be able to do a proper job.
