If your client is local, give local rates. If your client is international, give international rates. This is what I did in the past. You can contact with some local 3d artists to get a picture of your local rates. In both cases do not give a rate below acceptable rates otherwise you'll contribute to a race to the bottom…

So far I was able to charge local clients more by not mentioning…
