UK to Spanish website translation

We're launching a new website and we need approx 10,000 words of web content to translate into Spanish, as we are planning to launch a version of our website in Spain. Some has already been translated and will need reviewing instead.

The translations need to be accurate, as it's important for our search engine marketing. Any experience in the logistics industry would help but isn't essential.
Some of the content will need to be translated through a web portal, to which we'll give you access.

Many thanks!
