Need help cleaning a barbecue to pristine condition

I'm looking for someone to thoroughly clean my barbecue before summer grilling season. It’s a gas grill with separate burners and a detachable grill grate. I’d like the burners, lid, and trays wiped down, grates scrubbed, and any grease buildup removed. Please bring appropriate cleaning supplies and use non-abrasive cleaners to protect the finish. If possible, please also degrease the hood interior and check for any obvious maintenance issues. I’m flexible on date but would prefer a morning slot on a weekday and can accommodate 2 hours. No strong chemical odors, and I’d appreciate tips for ongoing maintenance.
