However, I will be moving to San Antonio in about a year and I am sure there are lots doing it there. But, even so, I am very people oriented and can probably still find enough to add a little income.

I disagree with that statement. While no identification system is perfect, microchips are very reliable over a long period of time. Do they occasionally fail? Sure.
As a former AKC field inspector, I have a lot of experience in identifying animals on premises. Tattooing used to be the the best prior to microchipping. Tattooing dogs is different than rabbits, you use a needle. However, what you tattoo on the dog IS a bit problematic. You can use your drivers license (which if you don't move COULD be looked up) or a registry generated #. Tattoos often fade over time and can be downright difficult or impossible to read. On black skinned dogs, they barely show up at all (like black Labs).
Years ago, I helped a lady who did exactly what you are thinking of doing. I let her tattoo all my dogs as her 'learning curve' and helped her sponsor some clinics at local dog events. Having additional help is often necessary, as owners don't know HOW to hold their dogs still and some dogs are extremely sensitive. It wasn't always easy work.
Still, it is of value and isn't a lot of $$$ to get started. However, I'll tell you, during my five year tenure as a field inspector, I became a FIRM advocate of microchipping for IDing animals. (and I don't know if they still do, but AVID donated scanners to any shelter that requested them.)
