Create/Update User Manual/Guide

Hello, I am needing a professional user manual/guide created for my ADSL2+ DSL modem from the one I have now as well as adding info to it for my retail sales. I am looking for it to be in a professional tabbed PDF format as well as a printable version to be included in the retail product box. This will take organizing the manual, formatting the manual adding images as appropriate and looking up some of the protocols and features the unit has and uses and articulate that into a professional manual/user guide just as you would see in a Sysco router. Must be fluent Native English speaker Understanding of ADSL2+ modems, features and setups for a competent user manual without allot of grammar changes or corrections needed as we develop the manual. I want someone whos knows about these types of units and will be fluent in understanding what the manual needs in it so a user can get the right info and understand the product and features.
