think it depends on how complex the design is.
I mean a simple design could be transferred without much trouble and others would take a lot more "copy paste"
I don't have a design yet to be honest with you, but, i have someone who can do that for me, so, i was looking what approx. price would be, to see if its worth it at all
I have to agree with tonemapped, thats a fair price range.
and like he said, those that do it a lot cheaper, usally think they can get away with doing a half job.
Never pay till you can see a demo of the completed job thats the safest way.
