Thanks ToniMichelle. I'm still unsure on how I'll handle this restoration. I spoke to aftercare in the SF store, and it was suggested I send it to Arrow for the lining first, then to Hermes for the rest of the bag. She mentioned interior cleaning wouldn't prevent the bag from being serviced in the future.
Like you said, somehow I'd feel better w Hermes taking care of all that they would and I send the bag to Arrow for finishing whatever Hermes wouldn't do. I'll share the process, my results and the costs when complete.
