Bass Tool Kit and Zipper Bag - Where to find???

With the holidays coming up, my sweet wife has asked me to make a list for Santa. Most of my items on the list are musical in nature. I got to thinking...I would really like a little bag or pouch to keep all my tools in. I have a bass string winder, some snips, allen wrenches, etc. So I go online to try and find one specifically for bassists...no dice. So now I'm thinking maybe I'm on to the next million-dollar idea, but before I go out and build a prototype, I figured I should ask the pros here on TB for help. Can anyone tell me if they know of a manufacturer of a little zippered tool kit for bass players?

Here's a really cool one for guitarists: GIGmate

The bag is cool, but it doesn't look like it will hold bass strings. I am basically looking for one that will be the same as this one, but big enough to hold a spare set or two of strings. As I mentioned above, I have most of the tools that come with this bag, I just need the bag or pouch to put them in. Anyone have something cool like this already? Or should I go and find a little tool bag somewhere, put some tools in it and market it on eBay and my website as the BASSMate Tool Kit???

 

Bump?
