Hi,
I am a developer with more than 12 years of experience with Visual Studio and Windows systems. I have already created a few VS add-ins and know how to integrate a window into the VS environment as well as a custom menu. By the way, what versions of VS should be supported? Please know that add-ins technology is deprecated in VS2013.
Regarding the price - I am aware that this is just a proof of concept, but there are some costs that should be covered (development is only a part of the whole work).
If you have any questions, do not hesitate to contact me.
