Need a gardener to clean a barbecue thoroughly

I'm looking for a reliable gardener to give my barbecue a thorough clean. It’s a standard charcoal grill, used regularly, and I’d like someone who can remove built-up grease, scrub grates, clean the lid and exterior, and check for any rust spots. I’d prefer eco-friendly cleaners and to keep the grill in good working condition. Please advise on whether the work can be completed in one session and if you can bring any necessary supplies. Flexible on start time, but aiming for a morning slot.
