Need someone to scarify a lawn in a small backyard

I'm looking for a reliable gardener to scarify my lawn in a small backyard. The job will involve aerating and removing dead moss and thatch to improve grass growth. I have a meter square lawn around 40-50 m2 in a suburban house in Ireland. Please bring or confirm a scarifier will work for a lawn of this size. I’d prefer if you could provide a rough plan for soil top-ups or overseeding if needed, and I’m hoping to schedule for a dry day in the coming week. Basic garden waste disposal is appreciated, and I’m happy to move any small items away from the workspace.
