Anyone know a dependable private taxi service?

Just to clarify-we use the buses, both local and cross country all the time when we travel. And we love them. But occasionally, especially with friends, we want to be able to get off the beaten path to pueblos, etc. and just hang around for awhile without having schlep luggage with us.

So for instance, we will be on a 10 day trip to Guadalajara and SM and then home here to GTO. We will be going to Guadalajara by bus and to SM from Guadalajara by bus, but then we would like to take a "tourist day" on the way home by hiring a driver to take us back to GTO. In this case, our place in SM has a driving service we can hire. But there are times here in GTO where we want to spend a day exploring at our own pace in places that are a bit harder to get to by bus and we would like to have someone we can hire to do that. Also, it is great to know someone for the airport run. Although it does sound much easier to just take a cab from the airport here to GTO than to pay the back and forth for pickup.

The other limiting factor a bit to buses for us with my sister is that she is a professional photographer and not only does she carry a lot of fairly fragile, expensive equipment that she is nervous about leaving in the luggage area of the bus, she is interested in hiring someone for the day who can take her around at her own for a day stopping when and where she wants to take photos.

Thanks for all the ideas-keep the names coming if you have someone else you would like to recommend. :)
