In general, we provide the service within 7-14 days of payment after receive of the final author communication. In a case of faster delivery, we charge additional 10% of the actual service cost for each day of acceleration. To answer this specific question, if the service is quoted as INR 1,000.00 for a 14-day delivery timeline, 4-day delivery will charge 14-410, 10-10% = 100%, 100% of additional payment, so the INR 1000.00 standard service may cost you INR 2000.00 in a case of 4-day premium delivery. The same service may cost you INR 1,400.00 in a case of 10-day premium delivery, INR 2,200.00 for 2-day premium delivery. We generally do not commit to premium deliveries targetted below-2-day timeline.
