This hybrid is inexcusable. Instead of “as per your request” say “in accordance with your request” or “in compliance with your request.” Maurice H. Weseen, Crowell’s Dictionary of English Grammar (1928).
When used to mean “according to” (per your request, per your order), the expression [per] is business jargon at its worst and should be avoided. Equally annoying is the phrase "as per.” Charles T. Brusaw, The Business Writer’s Handbook (1987).
So instead of writing:
As per our predictions, sales have increased.
As we predicted, sales have increased.
