Looking for someone experienced in Visual Studio to convert P3D plugin from 32 to 64bit

Hello, I would like to ask the community to see if there's any experienced programmers who specializes in Microsoft's Visual Studio. There was a 32-bit add-on for FSX and P3D v3 called PDF Kneeboard and it's such a must have tool for those who fly IFR/tubeliners. With the recent release of the 64-bit P3D v4, this add-on no longer works. It's basically a dll file. The source code is readily open and available for anyone who wishes to modify or add to it. So I was wondering if there's anyone here who may be interested in making this work with P3D v4. The source files are located here:

Since I know nothing about programming, this is no task for me. I've already contacted the author and asked for permission to do so and he said it would be no problem, since he has no time to continue with this anymore, he's making it open source to anyone who wishes to do so. I'm not sure what it would take to make this 64bit compatible. Do you need to rewrite the code or just modify some parts, or simply just recompile it using a 64bit compiler?
