Small sprayer for painting loose hardware with S-W enamel

I have hinges, door handles and metal brackets that need to be sprayed a particular S-W color to match wood trim painted with Pro Classic satin. What's the best small job sprayer or airbrush for the job? And wich product to use?

I saw online a company that will match any paint brand color in a rattle can. Also some S-W stores in Indiana once provided this service.
