I am looking for an English to German translator

We have a pdf booklet in English that needs to be translated in German and needs to be done in the beginning of July. It is a booklet about Concrete products and how to use them. A previous version of the booklet can be found here:

It is a booklet of roughly 18.000 words. As it is a big project we are looking for someone who can do this for a nice deal.
