Interesting. If I assume that a "4 hour round trip" means 2 hours each way and that an hour of driving equals 50 miles on average, then just the 200 miles is $117 at the IRS rate of $0.585 per mile. That leaves $83 for 4 hours of my time. I consider that reasonable. So, if this is above the base fee for the shop (the base fee has to pay for my time at the location, time to prepare, and time to submit), then I agree with your number. I also need to factor in how often the editor requires that I go back because they don't like a photo or something else.
For me, around $200.
