From my own perspective since I been doing such thing for months.
I started off pretty low 2$ hour. I'm no professional and I though its quite fair price because it took me quite some time to make something simple.
Besides I took this price based of this idea: I do a script entire day for someone else and then I can trade this 20$ for nice piece of map. win win
But at that time I was in so called "breakpoint" of scripting. I started seeing codes a little differently and how to make them. + making scripts for my own server and others increased the amount of different things I did.
Eventually If I had to I could make the same scripts twice as fast and even better. So I decided to increase the price to 4$/h.
Idk what happened like 2 months ago. But suddenly lot of several people wanted to make "hexera" copy + their ideas.
I got like 1 offer per day for doing this or that. At that time I didn't have any schedule or anything to keep track of how many offers I need to do and when.
So if I knew I gotta make script for someone tomorrow and maybe after tomorrow too, I just said "no time, should I contact you next week?".
Around that "me want scripts boom" I started increasing price $. Just to reduce the amount of people asking scripts from me. So I could do some of my own server too xD
Currently I ask 7€/h and I feel like stealing xD, but meh there are reasons why its gotten so high.
I guess, to see how much script should cost, post the idea of your script to Jobs thread. Maybe people suggest their prices or their idea of good price. (I know I will
)
Looking at the history of my trades. Seems like the average price for system like things fall between 30-40$. And it hasn't much changed since the time I did it for 2$/h and now latest sold price 6€/h
