Hello,

I'm no expert in this but I'm sure you'll find this helpful, at least I hope so

First I just made a simple search on download.com using this keyword 'dvd menu maker'
There I found a great looking software which I think is exactly what you are looking for.
There you can take almost any video output format, Trim, Crop and preview the video,
make a menu and ad sound to the menu. Then you can even use this software to burn
the DVD's.

If I were about to do what you are thinking about I would use this software and then
use kunaki.com

So my suggestion is that you use:
http://www.sothinkmedia.com/movie-dvd-maker/index.htm -- To make your DVD

http://www.kunaki.com -- To make your DVD's and send them individual! Just read more
about their service on the website and you'll see what they are about.

www.thediscbuddy.com or www.discmojo.com -- To automate Kunaki


If you get this all setup you can sell your product without worrying about a thing!
It will take care of it self

Hope this helps,
Ebbi
