Local Technology Company - Logo Ideas Needed

We're looking to take the confusion out of our appearance to the general public, on the face of our retail service centers. Help us re-brand !

Computers, by Walling Data

The gist of what we're doing.

Walling Data encompasses a number of divisions,  one of which provides local break/fix technology services within retail shops, which are small service depots for carry-in computer service as well as sattelite locations for dispatch of onsite technicians, etc.

Our corporate logo does not convey this very basic concept, in signage, on vehicles, or attire at all - it is confusing to the general public.

To that end, we would like to rebrand in a very generic fashion to this general public walk-in customer.

Local shops will be branded as follows,

Computers of Hickory

by Walling Data

Computers of Statesville

by Walling Data

Computers of Mooresville

by Walling Data

The main concern for conveying this in logo form is insuring large lighted signs convey the basics we are trying to get across - that this is a small technology shop offering something related to technology related repair. 

*One of my ideas was to rotate the existing logo sideways and modify the color scheme--inserting it beside the word computers on the signage.  Just an idea!  I am looking for dozens of creative concepts!

Corporate logo here:

- A very simple representation of "Computers of XXXX by Walling Data" that will work well in lighted sign form. 
- The word Computers should be prominently represented with the regional "of Hickory" and "By Walling Data" being much smaller.
- Computers and any associated creative-logo element will likely be represented in channel-cut channel-letters on the lighted sign while the remaining elements will be vinyl applied or extruded on a lighted can.
- Simplicity is key,  blending compatible color elements from the existing logo, as well as any reusable elements of the logo itself that will not interfere with the message we are trying to get across.

- Anything that will confuse a consumer,  that may lead to someone asking "what do ya'll do here" :)
