I think you will need to send Alejandro a copy of the confirmation of your reservation (so he can see that you are booked for the time period of your wedding). And then he should send you a pdf confirmation letter with your wedding date and wedding confirmation number. Once you start planning with what specific items you would like to add (such as rehearsal dinner menu, reception menu, any add-ons such as DJ, flowers), he'll create a quote for you when you get to a good point or near finalization. Congrats on setting the date!
