We do require payment in full before starting any order, once you get a full quote from us you can either send us a check or money order or we can email you an invoice and you can pay via credit card.  We process payments thru Paypal, you do not need a Paypal account we simply email you an invoice, there is a link in the email to pay the invoice.  Make sure to check the order to verify accuracy, then enter  your card information.  Once your order is placed Paypal will let us know and we will get your order going in the next run.  Once the run is started you cannot cancel or change the order.  Production time starts from when a run is started.
