Well im charging alot more than that for the reaver im doing lol.And on that note just remember that some people have no idea what you should charge, so don't be offended if someone lowballs you ... they might honestly not know what its worth. For example, if I hired you to weld some metal plates together, I know what that would cost and how long it should take. I do that stuff for a living and am familiar with it, but if I asked you to put together Titan and paint it up ... completely lost, never done it and I would start at $150 plus materials, paint, etc. Is this reasonable? I honestly don't know, but I do know that your time is worth money because you are doing something that I either can't because of lack of skills or won't because of lack of time. Work with them and try and explain why it costs what it does ... most people, if truly interested, will work with you.
I ran into the same problem as you Svart. I didnt really know what to charge etc. I looked around other commissioners and roughly based my prices on them + what i was willing to accept etc.
Then you add on material costs.
