Double Salary

How do I make it so people with ranks like vip, mod+, and so on get double salary on darkrp.

2 Things

Ulx - Ranks
Custom Jobs - Check Function to see if user has said rank and increase the pay amount

Yeah ULX ranks, also I don’t want them to have a custom job I want all jobs they use to have double salary like if they use the default citizen job they get double salary.
