Content (text mainly, image) editing layout application

Hi, a new text editing program is being made now in .NET C #, I need a Mac version. I am looking for a company with many positive refs, at least 50, and there will be an NDA. This is an ongoing job as a new company is set up for this application, with a website and forum, web2 version, evolution of product etc. The Mac version does not have to be exactly the same. You must have a track record for this type of work. It is possible it is not C at all on the Mac, I do not know the tech. The PC version is C# though, and all the code is in that, so I assume a conversion is possible fairly easily. There will be some web access in a later version (shared data for desktop apps) and also iphone. No communications at this stage as I am looking for a company for conversion work, at this level, not an individual freelancer. Thanks. This is original ad for the Windows version: This job requires a contract and NDA. It will protect both of us. I am looking to see who can do it then provide more details. Will be NDA and I need to see your references etc., and completed NDA type application jobs. Job is: This is a new utility that allows editing of multiple content areas (text, image upload, resize, not image edit). It has a graphic display, and some control of arrangement. There is more, to be revealed once NDA signed. It will run as a standard desktop application. Later will add online version so this is v1. There will also be a website to support it, some work there, again later on. Thanks
