Gardener (s) to maintain drought tolerant garden

Greetings all. We have an existing, rather small drought tolerant garden which is about 8 years old and doing quite well. We are in need of an individual or perhaps a couple to come by on a regular basis and take care if it. Perhaps they could add some plants if needed from time to time. If you have some recommendations for seasoned persons who are responsible and reliable as well as have a good knowledge of drought resistant plantings we would be grateful. Many thanks.
