You submit a form.
Which form depends on which tier. The Signature catalog has a short inquiry form on each build page (size, finish, contact). The DIY page is a direct order. Custom Elite has a longer application form because we want to understand the build before Sam takes the call.
Every submission goes to Amanda. None of them sit in a queue. None of them get auto-replied to with a "we'll be in touch" message and forgotten. She reads every one within one business day, often within an hour.
