Customized router firmware: put my company's logo in a firmware's graphic.

I have already a generic router's firmware. I want to customize it with my company logo and customize graphic and font as well. Goal is to obtain a original and personalized product to insert in our routers to sell to third parts. That must be totally different from original graphic version. BEFORE to commit the job to the project winner, I want to see an example about firmware final graphic version he/she wants to realize, and to make an NDA agreement with him/her as well. Menu must be multilanguage. When job'll be ended, I need an envoice about it. I have applied an example pic, a link with guide and the original firmware to customize. [login to view URL]
