I have never missed a turnaround date and often return the transcript before the standard 4- to 5-day turnaround time. My rates are industry average. Please email or call me for a custom rate quote.
I prefer to invoice using PayPal on the 1st and 15th of the month. (I pay all PayPal fees. There is no cost to you when remitting payment via PayPal.) However, other arrangements can be made if you prefer.
