If you have a small business or are looking for good copywriters, there are many copywriting services you could use. My recommendation is to begin with a freelance service such as freelancer.com or guru.com - you can get samples of previous work and determine if the writer is someone who will fit the style you want.
Another great option is to go to your local college or university and place ads for writers in the English or marketing departments. You could potentially get an intern or inexpensive student to write copy and perhaps find a great future employee that way.
Finding a copywriter service can take some time, and if you use a business you will end up paying their overhead costs as well as for the writing, but you also may get a few more guarantees and various styles. There are many talented writers searching for work, you might even consider placing ads in local classifieds and could find what you are looking for that way without having to go through a formal copywriting service. Be creative. You may find undiscovered talent simply by perusing blogs and forums. Just make sure you enter into any agreement as a limited contract or trial basis, or you may get stuck with a copywriter who has a different writing style or tone that you need.
