Gardening help for cleaning and maintaining a grave site

I’m looking for someone to help with maintaining a small grave site in my local cemetery. Tasks would include gently cleaning the stone, removing light debris, tidying nearby plantings, and applying a gentle moss and lichen removal where appropriate. I prefer careful, respectful handling of the stone and surrounding area, using non-abrasive products. The work would need to be done with consideration for weather and cemetery rules, and I’d appreciate guidance on repointing or sealing if you think it’s necessary. Timeframe is flexible, but I’d like someone reliable to visit every few months for routine upkeep.
