Hi Terrie,

Here are my thoughts:

It's basically an advertisement for your company, so I wouldn't expect people to share it or spread it virally. PPC may be your best option to promote it.

I agree with your suspicion that your video takes too long - way too long, in fact. I would suggest hiring someone who can help you create a higher quality video (i.e. footage and editing), also. I believe a more professional video would be  much more effective marketing tool.

Congrats on jumping into video, and hope this is helpful!
