Unfortunately, no. There are no guarantees in this business.
We could rewrite and/or polish the script to vastly improve it but that doesn’t necessarily guarantee a "Recommend," or that anyone in the industry will want to read or buy it.
That depends very much on the standard of the screenplay we’re given to work with.
We highly doubt you’ll find any company out there who says they can guarantee that the script will be a success—and if they do, we recommend you proceed with caution as more than likely they’re promising things just to take your money.
