If I reserve a date, how much money is due upfront?  Do we make monthly installments, or is payment due all at once?

Depending on the type of event you book, a deposit is required($400 for an Elope, $1500 for Formal Linen Flow or Garden Party Flow).  Another $1000 is due 6 months from the date of your event for both the Formal Linen Flow and Garden Party Flow, none is required for an Elope.  Your final payment is due 2 weeks before your event.  Your deposit and subsequent payments can be paid directly to your online invoice.
