Light Gardening Needed

I need someone who knows flowers, how to dead head flowers, cutback and shape plants, weed, and do checks and minor repair to light drip irrigation.
I'm 66, very active, but with some physical limitations (cant bend much since hip replacements etc) and need someone on a regular basis who will become familiar with flowers and can be proactive about what is needed. I can offer steady but irregular work, sometimes just a few hours every other week, sometimes as much as 5-8 hours a week.
I can pay $12/hr.

Please be personable, intelligent, helpful, and reliable! And available soon!
Leave your phone number and please tell me something about yourself, and have references. Thanks so much.
Thanks.
