Some of the test-coaching centers have pretty good track records, though you may not have one close. If he isn't a study-hound, then any guide book won't be as useful as having to actually go (prepared I hope) to a classroom to accomplish the preparation.
Or, find a college kid who broke 1400 and have him/her (now a HER just might do it) and pay them for tutoring.
And there are (good) colleges that haven't required SAT's for a while (unless they're reverted in the past 10 years).
The whole process is a bonafide part-time job for parents.
Best of luck.
