Hello
My name is Dejan and I have done tones of product 3D modeling and renderings. I am also doing 3D product interactive view for web use if needed.
Now about the pricing, this all depends on the product it self, how complicated is it, so some minimal price for simple shape products wold be 100$. In order to give the final price I wold have to see some photo or drawing of the product. The delivery day is usually 2-3 days, but again this depends on the product it self. The renderings are photo quality.
