$100 is nowhere near enough, but you estimate it at $105 with a $25 parking fee?
I estimated $130 as an absolute bare minimum for the operation I was familiar with, it was based on the real world.
Feel free to take away the parking for a location that doesn't have paid parking. But make sure to factor in that the mileage and labor hours must also go up if the depot is farther away.
The larger point is that it is an additional expense and operation that small businesses need to deal with at the busiest time of year.
