Having had multiple vehicles coated, I guess the question is what are you looking for? Ease of care in the future when it comes to washing, not having to wax/coat in the future after a wash to keep it shiny? If those are the reasons, then yes I would get it done by someone good at it. If you are looking for "protection" from chips, paint marring/swirls, brush pin striping then ceramic isn't the answer. PPF would be (although not 100% in those scenarios). If you are looking for both, PPF with a ceramic coat on top of it is the way to go. Only reason for the "asap" aspect is making it easier on whomever is doing this by minimizing the need for extensive paint correction before applying the PPF or ceramic coat (or both). Depending on what your dealer does for new car prep (usually a teenager with a low quality microfiber who washes and dries it after removing travel film), you may need paint correction anyway. I've done all three options, it just depends on your what you want (and of course budget).
