I had this long response, but it all ends up being.... why?... WHY was that design shown to the client? Who cares that the designer took 5 hours, he is bad, and slow... and you still sold it that way.
By the way, the file is a mess...
Not every design has to be a work of art... but
Bad design, performed at a snails pace is not a solid business plan.
Find a better designer, pay them a lot more per hour, expect workable files and design that will help your business grow. Find a back-up designer or 2, just in case.
