Need help cleaning barbecue thoroughly for summer cookouts

Hi there, I’m looking for someone to give my barbecue a deep clean before the weekend grill-outs. It’s a standard family-sized grill with a few stubborn grease spots on the grates and tray. I’d like the grates scrubbed, burners checked, and the exterior wiped down. Please bring your own cleaning supplies, or let me know what you require. I’d prefer a careful, detail-oriented approach and someone who can finish within a couple of hours. If possible, a quick tip on maintenance to prevent buildup would be great.
