It depends on the type of tattoo, a simple,small, black tattoo costs less and is also quicker to make. A large, colorful one costs more and also takes a long time to make.As for pain, it depends on the person. When I had my first tattoo done, I felt no discomfort at all.As for infection, if the tattoo is done in hygienic conditions and you take care of it afterwards, there should be no problems.My tattoo healed very nicely.
