Okay, let’s tackle this. So Amanda has 6 years of experience in billing, which is a specialized skill. The average billing salary in the US varies, but according to Indeed, the average billing specialist salary in Texas is around $40,000 per year. Considering her experience, I’d estimate her hourly rate to be around $20-$30 per hour, which is a reasonable rate for a billing professional with 6 years of experience. Let’s round that to $25, but since she’s in Texas, which has a relatively low cost of living, I’ll adjust that slightly to $20-$22. Given the lack of specific industry demand or company size, I’ll choose a conservative estimate of $22, but this rate is still on the lower end for someone with her experience.
