There's no shortage of places in Clod's town to buy business type gifts. Since it's more a matter of what will go over well with a small group, I'd go with dried fruits and/or nuts. They last for a bit at work, can be taken home to share, can be enjoyed on the go like trail mix and a basket of fresh product is usually welcome in any weather. There are multiple places to choose from. A quick search turned up this place with a user friendly website:
Home/nuts,
Dried fruits
You could also probably DIY from product bins at someplace like HEB. I've put out a selection of a half dozen dried fruits at company parties, along with plastic spoons and a package of small plastic cups for them, and they went like hotcakes.
