Those are the only two I have. I pulled one off the web of other projects people have done. I worked in a vocational school where the Auto shop teacher had a business on the side building cars for the drag strip. They also rebuilt old classic cars. They guided me to shops that powder coat. There are shops all over the Atlanta area.
I took in about 8 different parts and the guy charged me $80.00 It think. I know it was not over $100.00. It was anywhere from 40 to 80. I took in things like the screen for the fart fan in the bathroom. They have every kind of color you could want. They can make it look like chrome, silver, aluminum, you name it they can do it. The neatest job I saw was a guy brought in an old sinclair gas station pump and had it powder coated. It looked like it came from the factory floor when they were done. It is really amazing.
My advice is if you take in one item or several they usually charge the same. At least the guy I went with. He was the one that suggested I bring other stuff I could powder coat the same color.
This is a link I pulled off the web which will explain powder coating and it will show you pics.
