I've been translating documents for almost 10 years now as an aspect of my jobs, and I've grown accustomed to working efficiently and accurately. I've worked with everything from translating worksheets for children all the way through technical documents like an MSDS or product spec sheets for electronic components, so I'm confident in my ability to handle anything that is thrown at me. However, this will be my first time doing this on a freelance basis, and because of that I'm willing to work for your minimum budget figure in order to get my foot in the door and start getting some recommendations flowing on this site.
I won't be able to say how long the project will take without some more information on the content/density of the pages, but I would be able to let you know as soon as I saw the information.
