Cost of paint job on a small dent that is starting to rust

[matt.schilizik]

There is a small dent on the edge of the trunk in my 1997 Toyota Camry. Its about the size of a peanut and is now starting to rust.

I don't care about the dent. So if I take it to a body shop how much will it cost to just do a paint touch-up. What can I expect - will it paint job be smooth with the dent or will it be a just smeared with paint :?

Thanks!
