If you should require some studio magic above and beyond a 'dry' voice for your project, there is always the possibility of working together on a total audio package. If you are producing a radio commercial or similar project, Justin and Tiny Cow Studios offer jingle writing and composition services, editing (with sound effects) and mixing of your spot. The voice recording itself can be doctored up with any number of fancy effects and other processing (e.g., reverb) as is required.
Here are some examples of previous songs, jingles and goodies produced for radio in the USA and Ireland:
