Need Lawn Scarifying Service for My Garden

I'm looking for someone to scarify my lawn to help improve its health and appearance. The grass has become quite dense and patchy in some areas, and I want to remove the thatch buildup. Ideally, the job should be done with proper scarifying equipment, and I'd appreciate advice on any follow-up lawn care. The garden is medium-sized and located in a suburban area. Flexible on timing but would prefer a weekend appointment if possible.
