No. I don't mean this in a condescending way at all, but I'll state it flatly - the best thing to do is carefully hone your skills until you can cull 9.8 candidates from a stack of new books.
Take three books, pick the best by looking through magnification, holding the book at different angles under different lighting. Use cotton gloves. After picking the best, take notes on any flaws. Grab another stack of three, repeat. Do it again. Now take the three best books (one from each stack) and compare those. Rinse and repeat.
Sit on your submission until you reach the magic number of 25. Send in for pre-screen. See what the CGC has to say. Take more notes. Over time, you will be an expert and won't have to waste your money pressing fresh-out-the-box moderns.
Back in the day, I use to press everything as "insurance" but I was quite disappointed in the results because I:
A. Failed to properly screen them on my own.
B. Failed to pay the pre-screen fees for the pressing service.
Pressing isn't always magic, and it certainly isn't always cost-effective.
It's also very useful to learn how to differentiate between pressable and non-pressable defects. Some books can really benefit from a dry-clean and press. This has been proven time and time again. But plenty of people blindly send off moderns for pressing, thinking somehow that it guarantees a 9.8 when it certainly does not.
In fact, there were times when I was afraid to press a 9.8 candidate because of potential damage. If the book lays naturally and has a pristine spine, I figure it plays in the book's favor. Flat spines without the natural "fluff" may have the opposite effect. Conversely, there is the argument that pressed books are the new norm and have changed the expectations for a 9.8 grade.
Regardless, learning how to grade is a must in this hobby. It will save you LOTS of money.
