Setting max range as based on another field's value

Hi all,
Looking for someone that can add max value validation to a couple of fields that are based upon a % of another field’s value - either pulled from a field that displays that calculation or using the calculation itself d <= (a*0.25). Unfortunately, the built in rangeMax doesn’t allow pulling a value from another field or based on a calculation.

Simple example:
a. Estimated salary costs for locals
b. Estimated salary costs for expats
c. Estimated payments to loan out companies for locals
d. Estimated payments to loan out companies for expats (where d cannot exceed 25% of a or d <= (a*0.25)

There are three fields that will need this type of max range validation added. All three are on the same form ID. Job needs completion within 2-3 days.
