How much does it cost to have brake calipers painted?

I was interested in having my brake calipers painted professionally. I understand that it is much cheaper to do it yourself, but I do not have the kind of equipment to lift my car and remove the tires (if anyone knows of any cheap devices please mention). But how much would it cost to have my brake calipers professionally painted red. If it helps my car is a 2002 audi a6 2.7t and i have the standard brake calipers (meaning I have not upgraded them.) Lastly what is the difference between powder coating and regular painting and what do you suggest?
