AirPods sealing

I'm looking for a reliable contractor to make sell my AirPods Max . I already own the AirPods and need someone who is knowledgeable in such a service and able to do the job with the recommended turnaround time of more than 30 days. The sealant should be able to provide long lasting durability, integrity, and optimal performance. It should also be waterproof, sweat resistant and able to fully eliminate external sound disturbances. The budget for this project will be discussed with the chosen contractor.
